'Children of Israel' in the Bible

But I have a few things against thee: that thou hast, there, they that maintain the doctrine of Balaam, which taught in Balak to put occasion of sin before the children of Israel, that they should eat of meat dedicated unto idols, and to commit fornication.

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