“And he saith unto them, Is it lawful to do good on the sabbath days, or to do evil? to save life, or to kill? But they held their peace.”
Mark 3:4 — Greek Interlinear
Church Fathers on Mark 3:4
After confounding the Jews, who had blamed His disciples, for pulling the ears of corn on the sabbath day, by the example of David, the Lord now further bringing them to the truth, works a miracle on the sabbath; shewing that, if it is a pious deed to work miracles on the sabbath for the health of men, it is not wrong to do on the sabbath thing necessary for the body.
For, since He had defended the breaking of the sabbath, which they objected to His disciples, by an approved example, now they wish, by watching Him, to calumniate Himself, that they might accuse Him of a transgression, if He cured on the sabbath, of cruelty or of folly, if He refused.
But some one may wonder how Matthew could have said, that they themselves asked the Lord, if it was lawful to heal on the sabbath-day; when Mark rather relates that they were asked by our Lord, 'Is it lawful to do good on the sabbath-day, or to do evil?'
