2 Samuel 13:24

21 And when king David heard of these things he was exceedingly grieved: and he would not afflict the spirit of his son Ammon, for he loved him, because he was his firstborn.

22 But Absalom spoke not to Ammon neither good nor evil: for Absalom hated Ammon because he had ravished his sister Thamar.

23 And it came to pass after two years, that the sheep of Absalom were shorn in Baalhasor, which is near Ephraim: and Absalom invited all the king's sons:

24 And he came to the king, and said to him: Behold thy servant's sheep are shorn. Let the king, I pray, with his servants come to his servant.

25 And the king said to Absalom: Nay, my son, do not ask that we should all come, and be chargeable to thee. And when he pressed him, and he would not go, he blessed him.

26 And Absalom said: If thou wilt not come, at least let my brother Ammon, I beseech thee, come with us. And the king said to him: It is not necessary that he should go with thee.

27 But Absalom pressed him, so that he let Ammon and all the king's sons go with him. And Absalom made a feast as it were the feast of a king.
