Matthew 12:5
Or have you not read in the Law how on the Sabbath the priests in the temple profane the Sabbath and are guiltless? The second scriptural argument: the priests who perform the temple service on the Sabbath (slaughtering and burning offerings, Numbers 28:9–10) technically violate the Sabbath's prohibition on work but are not guilty of Sabbath violation. The temple service takes priority over the Sabbath because it serves a greater purpose. Jesus will apply this logic to himself in verse 6.
