'Fourth Generation' in the Bible

In the fourth generation your descendants will return here, for the sin of the Amorites has not yet reached its limit."

You shall not bow down to them or serve them, for I, the Lord, your God, am a jealous God, responding to the transgression of fathers by dealing with children to the third and fourth generations of those who reject me,

keeping loyal love for thousands, forgiving iniquity and transgression and sin. But he by no means leaves the guilty unpunished, responding to the transgression of fathers by dealing with children and children's children, to the third and fourth generation."

The Lord is slow to anger and abounding in loyal love, forgiving iniquity and transgression, but by no means clearing the guilty, visiting the iniquity of the fathers on the children until the third and fourth generations.'

After this Job lived 140 years; he saw his children and their children to the fourth generation.
