1 Corinthians 9:13

9:13 Don’t you know that those who serve in the temple eat food from the temple, and those who serve at the altar receive a part of the offerings?

Hebrews 7:13-14

7:13 Yet the one these things are spoken about belongs to a different tribe, and no one from that tribe has ever officiated at the altar. 7:14 For it is clear that our Lord is descended from Judah, yet Moses said nothing about priests in connection with that tribe.
