'Children of Israel' in the Bible

For I have not dwelt in a house since the day that I brought up the children of Israel out of Egypt, even to this day, but I went about in a tent and in a tabernacle.

In all my going about with all the children of Israel, did I speak a word with any of the tribes of Israel, whom I commanded to feed my people Israel, saying, Why build ye me not a house of cedars?

And the king called the Gibeonites, and spoke to them. (Now the Gibeonites were not of the children of Israel, but of the remainder of the Amorites; and the children of Israel had sworn to them; and Saul sought to smite them in his zeal for the children of Israel and Judah.)
