'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.

But I will take the kingdom out of his son's hand, and will give it unto thee, even ten tribes.

And crying to the Lord he said, O Lord my God, have you sent evil even on the widow whose guest I am, by causing her son's death?

Seest thou how Ahab humbleth himself before me? because he humbleth himself before me, I will not bring the evil in his days: but in his son's days will I bring the evil upon his house.
