Numbers 14:18

“The Lord [is] longsuffering, etc.] Towards all men, and especially towards his own people: and of great mercy, being abundant in goodness, and keeping mercy for thousands: forgiving iniquity and transgression, all sorts of sin: and by no means clearing [the guilty], visiting the iniquity of the fathers upon the children unto the third and fourth [generation]; which may seem to make against the plea of Moses for mercy and forgiveness; but the reason of these words being expressed seems to be, because they go along with the others in the passage referred to, and are no contradiction to the forgiving mercy of God in a way of justice; nor did Moses request to have the guilty cleared from…”

“Visiting the iniquity - These words may seem to be improperly mentioned, as being a powerful argument to move God to destroy this wicked people, and not to pardon them. It may be answered, that Moses useth these words together with the rest, because he would not sever what God had put together. But the truer answer seems to be, that these words are to be translated otherwise, And in destroying he will not utterly destroy, though he visit the iniquity of the fathers upon the children, unto the third and fourth generation. Numbers 14:20”
