'Sons' in the Bible

and if the ministration of the death, in letters, engraved in stones, came in glory, so that the sons of Israel were not able to look stedfastly to the face of Moses, because of the glory of his face -- which was being made useless,

and are not as Moses, who was putting a vail upon his own face, for the sons of Israel not stedfastly to look to the end of that which is being made useless,

and I will be to you for a Father, and ye -- ye shall be to Me for sons and daughters, saith the Lord Almighty.'
