Midrash sa Joel 4:14: Midrash Tehillim

Another interpretation regarding the Gittite. Isaiah said (Isaiah 5:16) "And the LORD of hosts shall be exalted in justice". When will the Lord be exalted? When he executes judgment on the nations of the world. What is written above this (Isaiah 5:15)? "And the mean man shall be brought down, and the mighty man shall be humbled". At that time, the Lord of hosts shall be exalted in judgment. Similarly, it is said (Ezekiel 38:18), "And it shall come to pass at the same time when Gog shall come against the land of Israel..." and Joel says (Joel 4:9-11) "Proclaim ye this among the nations; prepare war; stir up the mighty men; let all the men of war draw near; let them come up. Beat your plowshares into swords and your pruning hooks into spears; let the weak say, I am strong. Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O LORD." (Joel 4:2) "And I will also gather all nations, and will bring them down into the valley of Jehoshaphat, and will plead with them there for my people and for my heritage Israel, whom they have scattered among the nations, and parted my land." What is the valley called Jehoshaphat? It is the valley in which the Lord will judge the nations. Similarly, it is said (Joel 3:14), "Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision." The multitudes refer to (Jeremiah 25:33) "And the slain of the LORD shall be at that day from one end of the earth even unto the other end of the earth". And then (Joel 4:17), "So shall ye know that I am the LORD your God dwelling in Zion, my holy mountain." When will the Lord be seen upon Gath? Similarly, it is said (Micah 1:10), "Declare ye it not at Gath, weep ye not at all: in the house of Aphrah roll thyself in the dust." At that time, victory will be given to Him. "To the chief Musician upon Gittith" - there are four Gittiths: for the sons of Korah (Psalm 8), "For the Chief Musician upon Gittith", "Come down", and "For the Chief Musician, set to the Gittith" (Psalm 81) "Sing aloud unto God our strength, make a joyful noise unto the God of Jacob." This one is "upon Gittith."

I will praise the Lord with all my heart. As it is written (Isaiah 30:26), "And the light of the moon will be like the light of the sun, and the light of the sun will be sevenfold, like the light of the seven days, on the day that the Lord binds up the injuries of His people, and heals the wounds inflicted by His blow." This refers to the time when the Tower of Babel fell, which was caused by the wicked who prevent the light from shining in the world. It is also said (Judges 5:31), "Thus let all your enemies perish, O Lord!" At that time (ibid.), "And those who love Him are like the rising of the sun in its might." And at that time, God heals the brokenness of His people, as it is said (Isaiah 30:26), "On the day that the Lord binds up the injuries of His people." (Joel 4:14) "Multitudes, multitudes in the valley of decision." What is the valley of decision? It is a place where the judgment of those who fall there is final. As it is said (Jeremiah 25:33), "And the slain of the Lord shall be on that day from one end of the earth to the other end of the earth." (Until now they did not know.) (Psalm 110:6) "He will judge among the nations, He will fill them with corpses, He will crush the heads of many over the wide earth." In the future, rivers of blood will flow from the wicked, and the birds will come to drink from the stream of blood, as it is said (ibid. 7), "He will drink from the brook on the way." And the stream creates waves, and the wave comes to wash it away, and it lifts its head, as it is said (ibid.), "Therefore He will lift up His head." David said, "Praise and thanks I give for this." Therefore, we say Hallelujah.
