'Children of Israel' in the Bible

Whereas I have not dwelt in any house since the time that I brought up the children of Israel out of Egypt, even to this day, but have walked in a tent and in a tabernacle.

In all the places wherein I have walked with all the children of Israel spake I a word with any of the tribes of Israel, whom I commanded to feed my people Israel, saying, Why build ye not me an house of cedar?

And the king called the Gibeonites, and said unto them; (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal to the children of Israel and Judah.)
