“(non occ. sed v. Chrys. Hom. 39, in Matt) But being hungry, they ate simple food, not for pleasure, but on account of the necessity of nature. The Pharisees however, serving the figure and the shadow, accused the disciples of doing wrong. Wherefore there follows, But the Pharisees said unto him, Behold, why do they on the sabbath day that which is not lawful.”
“And he said unto them,.... By way of answer to their question, and which was a full one, and enough to silence them: have ye never read what David did; referring to the history in Sa1 21:1. when he had need: of bread, was in great necessity, and in the utmost distress: and was an hungered, he, and they that were with him? which was a justifiable reason for what he and his company did; as it was for the action of the disciples; being in a like case, and therefore very appropriate to the purpose; See Gill on Mat 12:3.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
