Numbers 14:17-19

And now, I pray thee, let the power of the Lord be great, according as thou hast spoken, saying, Jehovah is slow to anger, and abundant in lovingkindness, forgiving iniquity and transgression; and that will by no means clear the guilty, visiting the iniquity of the fathers upon the children, upon the third and upon the fourth generation. Pardon, I pray thee, the iniquity of this people according unto the greatness of thy lovingkindness, and according as thou hast forgiven this people, from Egypt even until now.
