Albert Barnes Commentary Psalms 106:43

"Many times did he deliver them; But they were rebellious in their counsel, And were brought low in their iniquity." — Psalms 106:43 (ASV)

Many times did he deliver them - From danger of invasion; from foreign arms; from entire overthrow. Numerous instances of this are recorded in the history of the Hebrew people.

But they provoked him with their counsel - This does not mean that they gave counsel or advice to God; but it refers to the counsel which they took among themselves; the plans which they formed. These were such as to offend God.

And were brought low for their iniquity - Margin, “impoverished or weakened.” The Hebrew word means to melt away, to pine; and hence, to decay, to be brought low. See (Job 24:24), where it is rendered brought low, and (Ecclesiastes 10:18), where it is rendered decayeth. The word does not occur elsewhere. The meaning is, that they were weakened; their national strength was exhausted as a punishment for their sins.
