'Children of Israel' in the Bible

But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balak to cast a stumbling-block before the children of Israel, to eat things sacrificed to idols, and to commit lewdness.

And I heard the number of them who were sealed: and there were sealed a hundred and forty four thousand of all the tribes of the children of Israel.

And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written on them, which are the names of the twelve tribes of the children of Israel.
