Hebrews 7:9-10
9-10 The Levite priests receive their gifts from the people. But we could say that Levi himself gave a tenth part of what he had to Melchizedek. When Abraham gave his tenth part to Melchizedek, it was like Levi was there inside him. At that time, Levi was not yet born, but Abraham was his ancestor.
