Numbers 14:17-19

17And now, I pray thee, let the power of the Lord be great, according as thou hast spoken, saying,

18The LORD is slow to anger, and plenteous in mercy, 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.

19Pardon, I pray thee, the iniquity of this people according unto the greatness of thy mercy, and according as thou hast forgiven this people, from Egypt even until now.
