'Children of Israel' in the Bible

But I have a few things against thee; for thou hast there those 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 fornication.

And I heard the number of those that were sealed; and there were an hundred forty and four thousand sealed out of all the tribes of the children of Israel.
