Genesis 18:15

Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(15) Sarah denied.—With strange inconsistency Sarah knows that the speaker is Divine, and that He perceived the thoughts that passed “within herself” in the retirement of the tent, and yet denies; but it was the inconsistency of fright. Struck with terror at the thought that she had ridiculed the promise of Jehovah, she offers no excuse, but takes refuge, as frightened people are apt to do, in falsehood. Gently reproved, the result was the building-up of her faith, just as Mary’s doubt was removed and her faith perfected by the angel’s words (Luke 1:34-37).

Matthew Henry's Concise Commentary

18:9-15 Where is Sarah thy wife? was asked. Note the answer, In the tent. Just at hand, in her proper place, occupied in her household concerns. There is nothing got by gadding. Those are most likely to receive comfort from God and his promises, who are in their proper place, and in the way of their duty, Lu 2:8. We are slow of heart to believe, and need line upon line to the same purport. The blessings others have from common providence, believers have from the Divine promise, which makes them very sweet, and very sure. The spiritual seed of Abraham owe their life, and joy, and hope, and all, to the promise. Sarah thinks this too good news to be true; she laughed, and therefore cannot as yet find in her heart to believe it. Sarah laughed. We might not have thought there was a difference between Sarah's laughter and Abraham's, ch. 17:17; but He who searches the heart, saw that the one sprung from unbelief, and the other from faith. She denied that she had laughed. One sin commonly brings in another, and it is not likely we shall strictly keep to truth, when we question the Divine truth. But whom the Lord loves he will rebuke, convict, silence, and bring to repentance, and if they sin before him.

Barnes' Notes on the Bible

The promise to Sarah. The men now enter upon the business of their visit. "Where is Sarah thy wife?" The jealousy and seclusion of later times had not yet rendered such an inquiry uncourteous. Sarah is within hearing of the conversation. "I will certainly return unto thee." This is the language of self-determination, and therefore suitable to the sovereign, not to the ambassador. "At the time of life;" literally the living time, seemingly the time of birth, when the child comes to manifest life. "Sarah thy wife shall have a son." Sarah hears this with incredulous surprise, and laughs with mingled doubt and delight. She knows that in the nature of things she is past child-bearing. "Is anything too hard for the Lord?" Sarah laughed within herself, within the tent and behind the speaker; yet to her surprise her internal feelings are known to him. She finds there is One present who rises above the sphere of nature. In her confusion and terror she denies that she laughed. But he who sees what is within, insists that she did laugh, at least in the thought of her heart. There is a beautiful simplicity in the whole scene. Sarah now doubtless received faith and strength to conceive.

Verse 16-33

The conference concerning Sodom. The human manner of the interview is carried out to the end. Abraham convoys his departing guests. The Lord then speaks, apparently debating with himself whether he shall reveal his intentions to Abraham. The reasons for doing so are assigned. First. Abraham shall surely become a nation great and mighty, and therefore has the interest of humanity in this act of retribution on Sodom. All that concerns man concerns him. Second. Blessed in him shall be all the nations of the earth. Hence, he is personally and directly concerned with all the dealings of mercy and judgment among the inhabitants of the earth. Third. "I have known him." The Lord has made himself known to him, has manifested his love to him, has renewed him after his own image; and hence this judgment upon Sodom is to be explained to him, that he may train his household to avoid the sins of this doomed city, "to keep the way of the Lord, to do justice and judgment; and all this to the further intent that the Lord may bring upon Abraham what he hath spoken of him." The awful judgments of the Lord on Sodom, as before on the antediluvian world, are a warning example to all who are spared or hear of them. And those who, notwithstanding these monuments of the divine vengeance, will cease to do justice and judgment, may be certain that they will not continue to enjoy the benefits of the covenant of grace. For all these reasons it is meet that the secret of Lord be with him Psalm 25:11.

Jamieson-Fausset-Brown Bible Commentary

12. Therefore Sarah laughed within herself—Long delay seems to have weakened faith. Sarah treated the announcement as incredible, and when taxed with the silent sneer, she added falsehood to distrust. It was an aggravated offense (Ac 5:4), and nothing but grace saved her (Ro 9:18).

Matthew Poole's Commentary

Sarah denied, from the sense of guilt, and the discovery of her shame, and the expectation of a sharp rebuke, both from this person, and from her husband.

Gill's Exposition of the Entire Bible

Then Sarah denied, saying, I laughed not,.... Some render the words, "Sarah lied" (z); and indeed it was no other than a lie, to say she did not laugh when she did; which she might be tempted to say in her confusion, partly because the back of the speaker was to her, and he could not see her, and partly because it was inward, and very little at least discoverable in her countenance:

for she was afraid; of the reproof of her husband; and of the charge of ill manners to a stranger; and especially as she had reason to believe that it was the Lord himself that had spoken these words, and therefore could gladly have excused herself, and wiped off the reproach:

and he said, nay, but thou didst laugh; it is not true what thou sayest, for thou didst certainly laugh; this he knew, being the omniscient God, notwithstanding, as he appeared as a man, his back was to her, and though her laughter was more internal than external.

(z) "mentita est", Drusius.

Geneva Study Bible

Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

EXEGETICAL (ORIGINAL LANGUAGES)

Cambridge Bible for Schools and Colleges

15. I laughed not] Sarah apparently emerges, in confusion and fear, to deny the guest’s statement. This occasions the fourth repetition of the word “laugh” in these four verses, by the short reply, “Nay, but thou didst laugh.”

Pulpit Commentary

Verse 15. - Then Sarah (who had overheard the conversation, and the charge preferred against her, and who probably now appeared before the stranger) denied, saying, I laughed not. Sarah s conduct will admit of no other explanation than that which the sacred narrative itself gives. For she was afraid. The knowledge that her secret thoughts had been deciphered must have kindled in her breast the suspicion that her visitor was none other than Jehovah. With this a sense of guilt would immediately assail her conscience for having cherished even a moment any doubt of the Divine word. In the consequent confusion of soul she tries what ever seems to be the first impulse of detected transgressions, viz., deception (cf. Genesis 3:12, 13). And he said, Nay; but thou didst laugh. With a directness similar to that which he employed in dealing with the first culprits in the garden, not contending in a multiplicity of words, but solemnly announcing that what she said was false. The silence of Sarah was an evidence of her conviction; her subsequent conception was a proof of her repentance and forgiveness.

CHAPTER 18:16-22 Genesis 18:15

Keil and Delitzsch Biblical Commentary on the Old Testament

During the meal, at which Abraham stood, and waited upon them as the host, they asked for Sarah, for whom the visit was chiefly intended. On being told that she was in the tent, where she could hear, therefore, all that passed under the tree in front of the tent, the one whom Abraham addressed as Adonai (my Lord), and who is called Jehovah in Genesis 18:13, said, "I will return to thee (חיּה כּעת) at this time, when it lives again" (חיּה, reviviscens, without the article, Ges. 111, 2b), i.e., at this time next year; "and, behold, Sarah, thy wife, will (then) have a son." Sarah heard this at the door of the tent; "and it was behind Him" (Jehovah), so that she could not be seen by Him as she stood at the door. But as the fulfilment of this promise seemed impossible to her, on account of Abraham's extreme age, and the fact that her own womb had lost the power of conception, she laughed within herself, thinking that she was not observed. But that she might know that the promise was made by the omniscient and omnipotent God, He reproved her for laughing, saying, "Is anything too wonderful (i.e., impossible) for Jehovah? at the time appointed I will return unto thee," etc.; and when her perplexity led her to deny it, He convicted her of falsehood. Abraham also had laughed at this promise (Genesis 17:17), and without receiving any reproof. For his laughing was the joyous outburst of astonishment; Sarah's, on the contrary, the result of doubt and unbelief, which had to be broken down by reproof, and, as the result showed, really was broken down, inasmuch as she conceived and bore a son, whom she could only have conceived in faith (Hebrews 11:11).
