Matthew 12:3-5

Young's Literal Translation

³ And he said to them, `Did ye not read what David did, when he was hungry, himself and those with him --

⁴ how he went into the house of God, and the loaves of the presentation did eat, which it is not lawful to him to eat, nor to those with him, except to the priests alone?

⁵ `Or did ye not read in the Law, that on the sabbaths the priests in the temple do profane the sabbath, and are blameless?
