'Children of Israel' in the Bible

But I have some things against you, because you have with you those who keep the teaching of Balaam, by whose suggestion Balak made the children of Israel go out of the right way, taking food which was offered to false gods, and going after the desires of the flesh.

She had a wall great and high, with twelve doors, and at the doors twelve angels; and names on them, which are the names of the twelve tribes of the children of Israel.
