“And Jesus answering them, said,.... For they brought the charge against the disciples to him, being desirous to know what he would say, and that they might have something to accuse him of; and who, at once, took up the cause of his disciples, and vindicated them, by observing what David did, when he, and his men were an hungry; how that he went into the tabernacle, and took the showbread, and ate of it, and gave it to his men, who also ate of it; which, according to the law, was only allowed to priests; and by taking notice of another instance, which this evangelist does not relate; namely, how on the sabbath days the priests, by doing various servile works, profaned the sabbath day, and yet were not charged with any blame; See Gill on Mat 12:3. See Gill on Mat 12:4. See Gill on Mat 12:5. . Luke 6:5 luk 6:5 luk 6:5 luk 6:5And he said unto them,.... He adds this at the close of the instances he gave, at the end of his vindication of his disciples, and discourse with the Pharisees, as a full answer to their cavils; that the son of man is Lord also of the sabbath; and may do what he will, and suffer his disciples to do whatever he pleases on that day; See Gill on Mat 12:8.”

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.
