Deuteronomy 14:1

That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.

For ye are all the children of God by faith in Christ Jesus.

They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.

Both the great and the small shall die in this land: they shall not be buried, neither shall men lament for them, nor cut themselves, nor make themselves bald for them:

That there came certain from Shechem, from Shiloh, and from Samaria, even fourscore men, having their beards shaven, and their clothes rent, and having cut themselves, with offerings and incense in their hand, to bring them to the house of the LORD.

And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God.

The Spirit itself beareth witness with our spirit, that we are the children of God:

But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: power: or, the right, or, privilege

Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, Ye are not my people, there it shall be said unto them, Ye are the sons of the living God. in...: or, instead of that

Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard. Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD.

And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.

And not for that nation only, but that also he should gather together in one the children of God that were scattered abroad.
