'Son's' in the Bible

However, I will not do it during your lifetime because of your father David; I will tear it out of your son’s hand.

I will take 10 tribes of the kingdom from his son’s hand and give them to you.

“Have you seen how Ahab has humbled himself before Me? I will not bring the disaster during his lifetime, because he has humbled himself before Me. I will bring the disaster on his house during his son’s lifetime.”
