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?

1 Corinthians 9:20-21

9:20 To the Jews I became like a Jew to gain the Jews. To those under the law I became like one under the law (though I myself am not under the law) to gain those under the law. 9:21 To those free from the law I became like one free from the law (though I am not free from God’s law but under the law of Christ) to gain those free from the law.
