'Sons' in the Bible

For it was fitting for Him, for whom are all things, and through whom are all things, in bringing many sons to glory, to perfect the author of their salvation through sufferings.

And those indeed of the sons of Levi who receive the priest’s office have commandment in the Law to collect a tenth from the people, that is, from their brethren, although these are descended from Abraham.

By faith Jacob, as he was dying, blessed each of the sons of Joseph, and worshiped, leaning on the top of his staff.

By faith Joseph, when he was dying, made mention of the exodus of the sons of Israel, and gave orders concerning his bones.

and you have forgotten the exhortation which is addressed to you as sons,“My son, do not regard lightly the discipline of the Lord,Nor faint when you are reproved by Him;

It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline?

But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons.
