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.
King James Version (KJV):
The LORD [is] longsuffering, and of great mercy, forgiving iniquity and transgression, and by no means clearing [the guilty], visiting the iniquity of the fathers upon the children unto the third and fourth [generation].
