Book of Joel Chapter 3 Vs. 19

 The Glorious Future of Judah

Egypt shall be a desolation, and Edom shall be a desolate wilderness, for the violence against the children of Judah, because they have shed innocent blood in their land. Joel 3:19

Egypt shall be... In contrast with the God-given abundance of Judah (Joel 3:18), the lands of her enemies (represented by Egypt and Edom) will be infertile (desolate and a desert waste). The reason for this severe judgment is their mistreatment of the people of Judah. Israel’s enemies are guilty of violence and of shedding innocent blood.

for the violence... Either in the land of Judah; as well in their own land, Egypt and Edom. This respects the violence and outrages committed by the antichristian states upon the true professors of the Christian religion.

Because they have... The Waldenses and Albigenses, and others, whose innocent blood, in great quantities, has been spilled by them.

Antichrist is represented as, drunk with the blood of the martyrs of Jesus, and in whom will be found the blood of all the prophets and saints. And for this reason ruin and destruction will come upon him and his followers, and blood will be given them to drink, for they are worthy (Rev. 17:6).

Egypt symbolizes the evil world. Edom was opposed to God from the beginning. This is a curse spoken against the enemies of God and His people.

If the Book of Joel was written in the ninth century b.c., the reference to Egypt in Joel 3:19 may allude to her acts of violence committed during the invasion of the Egyptian Pharaoh Shishak (ca. 926 b.c.; cf. 1Kgs. 14:25-26). But if the Book of Joel was written in the late preexilic or postexilic period, the invasion of Pharaoh Neco II may be in view (609 b.c.; cf. 2Kgs. 23:29-35). Obadiah also referred to Edomite sins against the Lord’s people (cf. Oba. 1:9-14).
