He went on from there and entered their synagogue.

Matthew 12:9. And having departed thence. This narrative and that which immediately precedes it have the same object; which is to show, that the scribes watched with a malicious eye for the purpose of turning into slander every thing that Christ did, and consequently that we need not wonder if men, whose minds were so depraved, were his implacable enemies.

Matthew Henry Presbyterian @wholebiblehenry

The Jewish teachers had corrupted many of the commandments, by interpreting them more loosely than they were intended; a mistake which Christ discovered and rectified (ch. 5) in his sermon on the mount: but concerning the fourth commandment, they had erred in the other extreme, and interpreted it too strictly.

And when he was departed thence,.... From the corn fields, where the disciples had plucked the ears of corn, and this conversation passed between Christ and the Pharisees about the violation of the sabbath, he went into their synagogue; not on the same sabbath day, as one might be led to conclude from the account of this evangelist, but on another sabbath, as Luke expresses it, Luk 6:6.
