Albert Barnes Commentary Psalms 108:11

"Hast not thou cast us off, O God? And thou goest not forth, O God, with our hosts." — Psalms 108:11 (ASV)

Wilt not thou, O God ... - This is taken from Psalms 60:10, with no change in the Hebrew, except that the word “thou” (in the first member of the verse) is omitted.
