'Descendants' in the Bible

For assuredly it is not to angels that He is continually reaching a helping hand, but it is to the descendants of Abraham.

And those of the descendants of Levi who receive the priesthood are authorized by the Law to take tithes from the people, that is, from their brethren, though these have sprung from Abraham.

Through faith Joseph, when he was near his end, made mention of the departure of the descendants of Israel, and gave orders about his own body.
