'Sons of Israel' in the Bible

"And shall win many of the sons of Israel to the Lord, their God.

When they heard this they went at early dawn to the Temple, and began to teach. Meantime when the high priest and his followers arrived, they summoned the Sanhedrin and all the Council of the Elders of the sons of Israel, and sent to the prison to fetch the apostles.

And in regard to Israel, Isaiah exclaims. Though the number of the sons of Israel be like the sands of the sea, it is but a remnant of those who shall be saved;

But I have a few things against you, because you have there some who hold to the teaching of Balaam, who taught Balak to put a stumbling-block before the sons of Israel, to eat food offered to idols, and to practise immorality.
