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

Volume 1-7
11. Hast cast us off. At the time, it seemed that God had forsaken His chosen people, but not so. He led the host of Israel against the impregnable heights of Edom, and they became servants of Israel (see on 1 Kings 11:15). Today He can bring us into the strong citadel of the enemy. Nothing can withstand those who trust in Him.
