Albert Barnes Commentary Psalms 85:5

"Wilt thou be angry with us for ever? Wilt thou draw out thine anger to all generations?" — Psalms 85:5 (ASV)

Wilt thou be angry with us for ever? – Your anger has continued so long that it seems as if it will never cease.

Wilt thou draw out thine anger – Will you protract or prolong it? The idea is that of a determined purpose in retaining his anger, as if his wrath would necessarily cease unless there were such a direct exercise of will.

To all generations – literally, “from generation to generation.” That is, so that not merely the generation which has sinned and brought down these tokens of displeasure will suffer, but the next, and the next, and the next, forever. The plea is that the judgment might end and not reach coming generations.
