Charles Spurgeon Commentary Matthew 12:9

"And he departed thence, and went into their synagogue:" — Matthew 12:9 (ASV)

The time arrived when the Sabbath question came up again in reference to our Lord’s own work among the sick and diseased.

Jesus set the example of attending public worship. The synagogues had no divine appointment to authorize them, but it must inherently be right and good to meet for the worship of God on His own day, and therefore Jesus was there. He had nothing to learn, yet He went up to the assembly on the day which the Lord God had hallowed.
