Every firstborn male shall be designated as holy to the Lord
Holy Gospel of Jesus Christ according to Saint Luke 02/22-24/:”When the time came for their purification according to the law of Moses, they brought him up to Jerusalem to present him to the Lord (as it is written in the law of the Lord, ‘Every firstborn male shall be designated as holy to the Lord’), and they offered a sacrifice according to what is stated in the law of the Lord, ‘a pair of turtle-doves or two young pigeons.”
King Melchizedek of Salem, priest of the Most High God, met Abraham, blessed him and to him Abraham apportioned ‘one-tenth of everything
Letter to the Hebrews 07/01-10/:”This ‘King Melchizedek of Salem, priest of the Most High God, met Abraham as he was returning from defeating the kings and blessed him’; and to him Abraham apportioned ‘one-tenth of everything’. His name, in the first place, means ‘king of righteousness’; next he is also king of Salem, that is, ‘king of peace’. Without father, without mother, without genealogy, having neither beginning of days nor end of life, but resembling the Son of God, he remains a priest for ever. See how great he is! Even Abraham the patriarch gave him a tenth of the spoils. And those descendants of Levi who receive the priestly office have a commandment in the law to collect tithes from the people, that is, from their kindred, though these also are descended from Abraham. But this man, who does not belong to their ancestry, collected tithes from Abraham and blessed him who had received the promises. It is beyond dispute that the inferior is blessed by the superior. In the one case, tithes are received by those who are mortal; in the other, by one of whom it is testified that he lives. One might even say that Levi himself, who receives tithes, paid tithes through Abraham, for he was still in the loins of his ancestor when Melchizedek met him.”
