Matthew 9:6 also uses 'Son of Man' to claim authority to forgive sins, reinforcing Jesus' divine authority over all things including Sabbath.

Mark 2:28 is the parallel synoptic verse, identical: the Son of Man is lord even of the Sabbath.

Luke 6:5 is the parallel account, stating the same truth: the Son of Man is lord of the Sabbath.

In John 5:17-23, Jesus claims His Father works on the Sabbath and that He has equal authority — showing the divine basis for being Lord of the Sabbath.
