Psalms 83:7

Gebal, and Ammon, and Amalek; the Philistines with the inhabitants of Tyre;

Gebal, Ammon, and Amalek are named among the peoples allied together against Israel. They belonged to a confederacy formed to drive Israel from its land, to destroy the nation, and to erase its name from remembrance. Their united alliance was opposition to God's people. The surrounding prayer calls upon God to judge these enemies.
