Matthew 12:3-5

3 Jesus answered,

4 David went into God’s house. He and those with him ate the bread that was made holy for God. It was against the law for them to eat that bread. Only the priests were allowed to eat it.

5 And have you not read in the law of Moses that on every Sabbath day the priests in the Temple break this law about the Sabbath day? But the priests are not wrong for doing that.
