Old Testament

The Second Book of the Kings
Chapter 17:29-41

However every nation continued to make gods of its own, and put them in the shrines on the high places which the Samaritans had made, every nation in the cities where they dwelt. The men of Babylon made Succoth Benoth, the men of Cuth made Nergal, the men of Hamath made Ashima, and the Avites made Nibhaz and Tartak; and the Sepharvites burned their children in fire to Adrammelech and Anammelech, the gods of Sepharvaim. So they feared the Lord, and from every class they appointed for themselves priests of the high places, who sacrificed for them in the shrines of the high places. They feared the Lord, yet served their own gods--according to the rituals of the nations from among whom they were carried away. To this day they continue practicing the former rituals; they do not fear the Lord, nor do they follow their statutes or their ordinances, or the law and commandment which the Lord had commanded the children of Jacob, whom He named Israel, with whom the Lord had made a covenant and charged them, saying: "You shall not fear other gods, nor bow down to them nor serve them nor sacrifice to them; but the Lord, who brought you up from the land of Egypt with great power and an outstretched arm, Him you shall fear, Him you shall worship, and to Him you shall offer sacrifice. And the statutes, the ordinances, the law, and the commandment which He wrote for you, you shall be careful to observe forever; you shall not fear other gods. And the covenant that I have made with you, you shall not forget, nor shall you fear other gods. But the Lord your God you shall fear; and He will deliver you from the hand of all your enemies." However they did not obey, but they followed their former rituals. So these nations feared the Lord, yet served their carved images; also their children and their children's children have continued doing as their fathers did, even to this day.

New Testament

The Epistle to the Hebrews
Chapter 7:1-10

For this Melchizedek, king of Salem, priest of the Most High God, who met Abraham returning from the slaughter of the kings and blessed him, to whom also Abraham gave a tenth part of all, first being translated "king of righteousness," and then also king of Salem, meaning "king of peace," without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, remains a priest continually. Now consider how great this man was, to whom even the patriarch Abraham gave a tenth of the spoils. And indeed those who are of the sons of Levi, who receive the priesthood, have a commandment to receive tithes from the people according to the law, that is, from their brethren, though they have come from the loins of Abraham; but he whose genealogy is not derived from them received tithes from Abraham and blessed him who had the promises. Now beyond all contradiction the lesser is blessed by the better. Here mortal men receive tithes, but there he receives them, of whom it is witnessed that he lives. Even Levi, who receives tithes, paid tithes through Abraham, so to speak, for he was still in the loins of his father when Melchizedek met him.
