Charles Ellicott Commentary Psalms 79:1

"O God, the nations are come into thine inheritance; Thy holy temple have they defiled; They have laid Jerusalem in heaps." — Psalms 79:1 (ASV)

Inheritance. — Probably intended to embrace both land and people. (Exodus 15:17; Psalms 74:2; and others.)

Heaps — that is, ruins. (Jeremiah 26:18; and in the singular, Micah 1:6.)
