Genesis 14:18-20 (NLT) — 18 And Melchizedek, the king of Salem and a priest of God Most High, brought Abram some bread and wine. 19 Melchizedek blessed Abram with this blessing: “Blessed be Abram by God Most High, Creator of heaven and earth. 20 And blessed be God Most High, who has defeated your enemies for you.” Then Abram gave Melchizedek a tenth of all the goods he had recovered.
Psalm 110:1-4 (NLT) — 1 The LORD said to my Lord, “Sit in the place of honor at my right hand until I humble your enemies, making them a footstool under your feet.” 2 The LORD will extend your powerful kingdom from Jerusalem; you will rule over your enemies. 3 When you go to war, your people will serve you willingly. You are arrayed in holy garments, and your strength will be renewed each day like the morning dew. 4 The LORD has taken an oath and will not break his vow: “You are a priest forever in the order of Melchizedek.”
Hebrews 7:1-3 (NLT) — 1 This Melchizedek was king of the city of Salem and also a priest of God Most High. When Abraham was returning home after winning a great battle against the kings, Melchizedek met him and blessed him. 2 Then Abraham took a tenth of all he had captured in battle and gave it to Melchizedek. The name Melchizedek means “king of justice,” and king of Salem means “king of peace.” 3 There is no record of his father or mother or any of his ancestors—no beginning or end to his life. He remains a priest forever, resembling the Son of God.
