Joel 3:10
Beat your plowshares into swords and your pruning hooks into spears. Let the weak say, 'I am strong!'
Beat your plowshares into swords
This phrase is a reversal of the more familiar prophetic vision found in Isaiah 2:4 and Micah 4:3, where nations are called to beat their swords into plowshares. Here, the prophet Joel calls for the opposite transformation, indicating a time of war rather than peace. The Hebrew word for "plowshares" is "’ēt," which refers to the cutting edge of a plow, a tool for cultivation and growth. The transformation into "swords" (Hebrew: "ḥereb") signifies a shift from agricultural productivity to military readiness. This call to arms reflects the urgency and seriousness of the impending divine judgment and the need for the people to prepare for the spiritual battle that lies ahead.

and your pruning hooks into spears
Similar to the previous phrase, this part of the verse continues the theme of transformation from tools of peace to instruments of war. "Pruning hooks" (Hebrew: "mazmerah") are tools used for trimming vines, symbolizing care and nurturing. The conversion into "spears" (Hebrew: "romach") further emphasizes the necessity of readiness for conflict. This imagery underscores the gravity of the situation Joel is addressing, where the usual activities of life are interrupted by the call to defend and uphold God's justice. It serves as a metaphor for the spiritual vigilance required of God's people in times of moral and spiritual crisis.

Let the weak say, ‘I am strong!’
This phrase is a powerful declaration of faith and divine empowerment. The Hebrew word for "weak" is "ḥālâ," which can mean sick, weak, or afflicted. In the context of this verse, it represents those who feel inadequate or powerless. The command for the weak to proclaim, "I am strong" (Hebrew: "gibbôr"), is an encouragement to rely on God's strength rather than their own. It is a call to courage and trust in God's provision and might, reminiscent of Paul's declaration in 2 Corinthians 12:10, "For when I am weak, then I am strong." This transformation from weakness to strength is not through human effort but through divine intervention and empowerment, reminding believers that their true strength lies in their relationship with God.

The Gospel Day Seen in Prophecy.
Upon reading the account of man's creation in the first chapters of Genesis we conclude that he enjoyed perfect peace and happiness. From the beautiful description given there of the garden of Eden--man's abode--we understand that God was interested in his felicity. In the nature of created things he could retain this happiness only by obedience to the Creator's laws. By a subtle foe he was induced to transgress those laws and thus became acquainted with sin and sorrow. After the transgression he

Whether the Judgment Will Take Place in the Valley of Josaphat?
Objection 1: It would seem that the judgment will not take place in the valley of Josaphat or in the surrounding locality. For at least it will be necessary for those to be judged to stand on the ground, and those alone to be raised aloft whose business it will be to judge. But the whole land of promise would not be able to contain the multitude of those who are to be judged. Therefore it is impossible for the judgment to take place in the neighborhood of that valley. Objection 2: Further, to Christ

Post-Millennialism Refuted.
The post-millennial position rests largely upon a mis-translation. In Matt. 13:39 we read "The harvest is the end of the world," and again in Matt. 24:3--"And as He sat upon the Mount of Olives, the disciples came unto Him privately, saying, Tell us, when shall these things be? and what shall be the sign of Thy coming, and of the end of the world?" Now the Greek word which is used in the above passages is entirely different from the one found in John 3:16--"God so loved the Kosmos." In the verses

The Battle of Armageddon.
The Battle of Armageddon! What extravagant speculations have been indulged concerning it! What unscriptural theories have been entertained respecting it! To begin with; this appears from the term employed. Nowhere in the Bible do we read of "The Battle of Armageddon." The Scriptural expression is "The Battle of that great day of God Almighty" (Rev. 16:14). This Battle of the great day of God Almighty will bring the Tribulation period to a close and will witness the return of Christ to the earth to

The Twelve Minor Prophets.
1. By the Jewish arrangement, which places together the twelve minor prophets in a single volume, the chronological order of the prophets as a whole is broken up. The three greater prophets, Isaiah, Jeremiah, and Ezekiel, stand in the true order of time. Daniel began to prophesy before Ezekiel, but continued, many years after him. The Jewish arrangement of the twelve minor prophets is in a sense chronological; that is, they put the earlier prophets at the beginning, and the later at the end of the

The Valley of Hinnom.
A great part of the valley of Kedron was called also the 'Valley of Hinnom.' Jeremiah, going forth into the valley of Hinnom, went out by the gate "Hacharsith, the Sun-gate," Jeremiah 19:2; that is, the Rabbins and others being interpreters, 'by the East-gate.' For thence was the beginning of the valley of Hinnom, which, after some space, bending itself westward, ran out along the south side of the city. There is no need to repeat those very many things, which are related of this place in the Old

The Prophecy of Obadiah.
We need not enter into details regarding the question as to the time when the prophet wrote. By a thorough argumentation, Caspari has proved, that he occupies his right position in the Canon, and hence belongs to the earliest age of written prophecy, i.e., to the time of Jeroboam II. and Uzziah. As bearing conclusively against those who would assign to him a far later date, viz., the time of the exile, there is not only the indirect testimony borne by the place which this prophecy occupies in

The Figurative Language of Scripture.
1. When the psalmist says: "The Lord God is a sun and shield" (Psa. 84:11), he means that God is to all his creatures the source of life and blessedness, and their almighty protector; but this meaning he conveys under the figure of a sun and a shield. When, again, the apostle James says that Moses is read in the synagogues every Sabbath-day (Acts 15:21), he signifies the writings of Moses under the figure of his name. In these examples the figure lies in particular words. But it may be embodied

Interpretation of Prophecy.
1. The scriptural idea of prophecy is widely removed from that of human foresight and presentiment. It is that of a revelation made by the Holy Spirit respecting the future, always in the interest of God's kingdom. It is no part of the plan of prophecy to gratify vain curiosity respecting "the times or the seasons which the Father hath put in his own power." Acts 1:7. "Comfort ye, comfort ye my people, saith your God"--this is its key-note. In its form it is carefully adapted to this great end.
