Exodus 34:7-9

Young's Literal Translation

⁷ keeping kindness for thousands, taking away iniquity, and transgression, and sin, and not entirely acquitting, charging iniquity of fathers on children, and on children's children, on a third [generation], and on a fourth.'

⁸ And Moses hasteth, and boweth to the earth, and doth obeisance,

⁹ and saith, `If, I pray Thee, I have found grace in Thine eyes, O my Lord, let my Lord, I pray Thee, go in our midst (for it [is] a stiff-necked people), and thou hast forgiven our iniquity and our sin, and hast inherited us.'
