Then why don't you read it. Then you'd know where the house of Judah and house of Israel came from.
1Kgs 11:7-13 (AKJV/PCE)
(11:7) Then did Solomon build an high place for Chemosh, the abomination of Moab, in the hill that [is] before Jerusalem, and for Molech, the abomination of the children of Ammon. (11:8) And likewise did he for all his strange wives, which burnt incense and sacrificed unto their gods. (11:9) ¶ And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel, which had appeared unto him twice, (11:10) And had commanded him concerning this thing, that he should not go after other gods: but he kept not that which the LORD commanded. (11:11) Wherefore the LORD said unto Solomon, Forasmuch as this is done of thee, and thou hast not kept my covenant and my statutes, which I have commanded thee, I will surely rend the kingdom from thee, and will give it to thy servant. (11:12) Notwithstanding in thy days I will not do it for David thy father's sake: [but] I will rend it out of the hand of thy son. (11:13) Howbeit I will not rend away all the kingdom; [but] will give one tribe to thy son for David my servant's sake, and for Jerusalem's sake which I have chosen.
1Kgs 11:30-43 (AKJV/PCE)
(11:30) And Ahijah caught the new garment that [was] on him, and rent it [in] twelve pieces: (11:31) And he said to Jeroboam, Take thee ten pieces: for thus saith the LORD, the God of Israel, Behold, I will rend the kingdom out of the hand of Solomon, and will give ten tribes to thee: (11:32) (But he shall have one tribe for my servant David's sake, and for Jerusalem's sake, the city which I have chosen out of all the tribes of Israel (11:33) Because that they have forsaken me, and have worshipped Ashtoreth the goddess of the Zidonians, Chemosh the god of the Moabites, and Milcom the god of the children of Ammon, and have not walked in my ways, to do [that which is] right in mine eyes, and [to keep] my statutes and my judgments, as [did] David his father. (11:34) Howbeit I will not take the whole kingdom out of his hand: but I will make him prince all the days of his life for David my servant's sake, whom I chose, because he kept my commandments and my statutes: (11:35) But I will take the kingdom out of his son's hand, and will give it unto thee, [even] ten tribes. (11:36) And unto his son will I give one tribe, that David my servant may have a light alway before me in Jerusalem, the city which I have chosen me to put my name there. (11:37) And I will take thee, and thou shalt reign according to all that thy soul desireth, and shalt be king over Israel. (11:38) And it shall be, if thou wilt hearken unto all that I command thee, and wilt walk in my ways, and do [that is] right in my sight, to keep my statutes and my commandments, as David my servant did; that I will be with thee, and build thee a sure house, as I built for David, and will give Israel unto thee. (11:39) And I will for this afflict the seed of David, but not for ever. (11:40) Solomon sought therefore to kill Jeroboam. And Jeroboam arose, and fled into Egypt, unto Shishak king of Egypt, and was in Egypt until the death of Solomon. (11:41) ¶ And the rest of the acts of Solomon, and all that he did, and his wisdom, [are] they not written in the book of the acts of Solomon? (11:42) And the time that Solomon reigned in Jerusalem over all Israel [was] forty years. (11:43) And Solomon slept with his fathers, and was buried in the city of David his father: and Rehoboam his son reigned in his stead.
