You shall not bow down yourself to them, nor serve them: for I the LORD your God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;

Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.

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.

You shall not bow down yourself unto them, nor serve them: for I the LORD your God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,

And the LORD said unto Jehu, Because you have done well in executing that which is right in my eyes, and have done unto the house of Ahab according to all that was in my heart, your children of the fourth generation shall sit on the throne of Israel.

This was the word of the LORD which he spoke unto Jehu, saying, Your sons shall sit on the throne of Israel unto the fourth generation. And so it came to pass.
