Charles H. Spurgeon on Psalms 79:8

"O remember not against us former iniquities." The Jews have a saying, that there is no punishment happens to Israel, but there is an ounce in it for the sin of the calf; their meaning is, that this is always remembered and visited, according to Exodus 32:34; the phrase may take in all the sins of former persons, their ancestors, and of former times, from age to age, they had continued in, which had brought ruin upon them; and all their own sins of nature and of youth, all past ones to the present time.—John Gill.
