4:11-16 Observe the end proposed: rest spiritual and eternal; the rest of grace here, and glory hereafter; in Christ on earth, with Christ in heaven. After due and diligent labour, sweet and satisfying rest shall follow; and labour now, will make that rest more pleasant when it comes. Let us labour, and quicken each other to be diligent in duty. The Holy Scriptures are the word of God. When God sets it home by his Spirit, it convinces powerfully, converts powerfully, and comforts powerfully. It makes a soul that has long been proud, to be humble; and a perverse spirit, to be meek and obedient. Sinful habits, that are become as it were natural to the soul, and rooted deeply in it, are separated and cut off by this sword. It will discover to men their thoughts and purposes, the vileness of many, the bad principles they are moved by, the sinful ends they act to. The word will show the sinner all that is in his heart. Let us hold fast the doctrines of Christian faith in our heads, its enlivening principles in our hearts, the open profession of it in our lips, and be subject to it in our lives. Christ executed one part of his priesthood on earth, in dying for us; the other he executes in heaven, pleading the cause, and presenting the offerings of his people. In the sight of Infinite Wisdom, it was needful that the Saviour of men should be one who has the fellow-feeling which no being but a fellow-creature could possibly have; and therefore it was necessary he should actual experience of all the effects of sin that could be separated from its actual guilt. God sent his own Son in the likeness of sinful flesh, Ro 8:3; but the more holy and pure he was, the more he must have been unwilling in his nature to sin, and must have had deeper impression of its evil; consequently the more must he be concerned to deliver his people from its guilt and power. We should encourage ourselves by the excellence of our High Priest, to come boldly to the throne of grace. Mercy and grace are the things we want; mercy to pardon all our sins, and grace to purify our souls. Besides our daily dependence upon God for present supplies, there are seasons for which we should provide in our prayers; times of temptation, either by adversity or prosperity, and especially our dying time. We are to come with reverence and godly fear, yet not as if dragged to the seat of justice, but as kindly invited to the mercy-seat, where grace reigns. We have boldness to enter into the holiest only by the blood of Jesus; he is our Advocate, and has purchased all our souls want or can desire.

12. For—Such diligent striving (Heb 4:11) is incumbent on us FOR we have to do with a God whose "word" whereby we shall be judged, is heart-searching, and whose eyes are all-seeing (Heb 4:13). The qualities here attributed to the word of God, and the whole context, show that it is regarded in its JUDICIAL power, whereby it doomed the disobedient Israelites to exclusion from Canaan, and shall exclude unbelieving so-called Christians from the heavenly rest. The written Word of God is not the prominent thought here, though the passage is often quoted as if it were. Still the word of God (the same as that preached, Heb 4:2), used here in the broadest sense, but with special reference to its judicial power, INCLUDES the Word of God, the sword of the Spirit with double edge, one edge for convicting and converting some (Heb 4:2), and the other for condemning and destroying the unbelieving (Heb 4:14). Re 19:15 similarly represents the Word's judicial power as a sharp sword going out of Christ's mouth to smite the nations. The same word which is saving to the faithful (Heb 4:2) is destroying to the disobedient (2Co 2:15, 16). The personal Word, to whom some refer the passage, is not here meant: for He is not the sword, but has the sword. Thus reference to Joshua appropriately follows in Heb 4:8.

quick—Greek, "living"; having living power, as "the rod of the mouth and the breath of the lips" of "the living God."

powerful—Greek, "energetic"; not only living, but energetically efficacious.

sharper—"more cutting."

two-edged—sharpened at both edge and back. Compare "sword of the Spirit … word of God" (Eph 6:17). Its double power seems to be implied by its being "two-edged." "It judges all that is in the heart, for there it passes through, at once punishing [unbelievers] and searching [both believers and unbelievers]" [Chrysostom]. Philo similarly speaks of "God passing between the parts of Abraham's sacrifices (Ge 15:17, where, however, it is a 'burning lamp' that passed between the pieces) with His word, which is the cutter of all things: which sword, being sharpened to the utmost keenness, never ceases to divide all sensible things, and even things not perceptible to sense or physically divisible, but perceptible and divisible by the word." Paul's early training, both in the Greek schools of Tarsus and the Hebrew schools at Jerusalem, accounts fully for his acquaintance with Philo's modes of thought, which were sure to be current among learned Jews everywhere, though Philo himself belonged to Alexandria, not Jerusalem. Addressing Jews, he by the Spirit sanctions what was true in their current literature, as he similarly did in addressing Gentiles (Ac 17:28).

piercing—Greek, "coming through."

even to the dividing asunder of soul and spirit—that is, reaching through even to the separation of the animal soul, the lower part of man's incorporeal nature, the seat of animal desires, which he has in common with the brutes; compare the same Greek, 1Co 2:14, "the natural [animal-souled] man" (Jude 19), from the spirit (the higher part of man, receptive of the Spirit of God, and allying him to heavenly beings).

and of the joints and marrow—rather, "(reaching even TO) both the joints (so as to divide them) and marrow." Christ "knows what is in man" (Joh 2:25): so His word reaches as far as to the most intimate and accurate knowledge of man's most hidden parts, feelings, and thoughts, dividing, that is, distinguishing what is spiritual from what is carnal and animal in him, the spirit from the soul: so Pr 20:27. As the knife of the Levitical priest reached to dividing parts, closely united as the joints of the limbs, and penetrated to the innermost parts, as the marrows (the Greek is plural); so the word of God divides the closely joined parts of man's immaterial being, soul and spirit, and penetrates to the innermost parts of the spirit. The clause (reaching even to) "both the joints and marrow" is subordinate to the clause, "even to the dividing asunder of soul and spirit." (In the oldest manuscripts as in English Version, there is no "both," as there is in the clause "both the joints and … which marks the latter to be subordinate). An image (appropriate in addressing Jews) from the literal dividing of joints, and penetrating to, so as to open out, the marrow, by the priest's knife, illustrating the previously mentioned spiritual "dividing of soul from spirit," whereby each (soul as well as spirit) is laid bare and "naked" before God; this view accords with Heb 4:13. Evidently "the dividing of the soul from the spirit" answers to the "joints" which the sword, when it reaches unto, divides asunder, as the "spirit" answers to the innermost "marrow." "Moses forms the soul, Christ the spirit. The soul draws with it the body; the spirit draws with it both soul and body." Alford's interpretation is clumsy, by which he makes the soul itself, and the spirit itself, to be divided, instead of the soul from the spirit: so also he makes not only the joints to be divided asunder, but the marrow also to be divided (?). The Word's dividing and far penetrating power has both a punitive and a healing effect.

discerner of the thoughts—Greek, "capable of judging the purposes."

intents—rather, "conceptions" [Crellius]; "ideas" [Alford]. AS the Greek for "thoughts" refers to the mind and feelings, so that for "intents," or rather "mental conceptions," refers to the intellect.
