Numbers 14:18-19

18‘The Lord is longsuffering and abundant in mercy, forgiving iniquity and transgression; but He by no means clears the guilty, visiting the iniquity of the fathers on the children to the third and fourth generation.’

19Pardon the iniquity of this people, I pray, according to the greatness of Your mercy, just as You have forgiven this people, from Egypt even until now.”
