'Sons' in the Bible

But I have a few things against you, because you have there some [among you] who are holding to the [corrupt] teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel, [enticing them] to eat things that had been sacrificed to idols and to commit [acts of sexual] immorality.

And I heard how many were sealed, a hundred and forty-four thousand; [twelve thousand] sealed from every tribe of the sons of Israel:

It had a massive and high wall, with twelve [large] gates, and at the gates [were stationed] twelve angels; and on the gates the names of the twelve tribes of the sons of Israel were written.
