'House of Israel' in the Bible

When Rehoboam arrived in Jerusalem, he mobilized 180,000 choice warriors from the entire house of Judah and the tribe of Benjamin to fight against the house of Israel to restore the kingdom to Rehoboam son of Solomon.

His servants said to him, “Consider this: we have heard that the kings of the house of Israel are merciful kings. So let’s put sackcloth around our waists and ropes around our heads, and let’s go out to the king of Israel. Perhaps he will spare your life.”
