Kings III 11:32 In-Context

30 And Achia laid hold of his new garment that was upon him, and tore it twelve pieces:
31 and he said to Jeroboam, Take to thyself ten pieces, for thus saith the Lord God of Israel, Behold, I rend the kingdom out of the hand of Solomon, and will give thee ten tribes.
32 Yet he shall have two tribes, for my servant David's sake, and for the sake of Jerusalem, the city which I have chosen out of all the tribes of Israel.
33 Because he forsook me, and sacrificed to Astarte the abomination of the Sidonians, and to Chamos, and to the idols of Moab, and to their king the abomination of the children of Ammon, and he walked not in my ways, to do that which was right before me, as David his father .
34 Howbeit I will not take the whole kingdom out of his hand, (for I will certainly resist him all the days of his life,) for David my servant's sake, whom I have chosen.
