10:11-12 Whoever divorces . . . and marries someone else commits adultery: The parallel in Luke 16:18 agrees with Mark and mentions no exceptions to this prohibition of divorce, while Matthew’s parallel account allows an exception in cases of infidelity (Matt 19:9; see also Matt 5:32). Paul also allows an exception if an unbelieving partner deserts the marriage (1 Cor 7:15). Mark’s account focuses on the core principles—God hates divorce (Mal 2:16), marriage is meant to be for life, and divorce betrays the divine purpose of marriage.

10:1-2 The Pharisees’ question about divorce was much debated in Judaism, but it had a hostile purpose as they tried to trap Jesus (see 2:16, 18, 24; 7:5; 8:11; 12:13). John the Baptist was beheaded over his teaching that Herod Antipas’s divorce and remarriage was unlawful (6:18-19), and according to the Jewish historian Josephus, John was martyred close to Jesus’ current location east of the Jordan River, at Herod Antipas’s fortress at Machaerus (see 6:28; Josephus, Antiquities 18.5.2). If Jesus answered in agreement with John the Baptist, the Pharisees could indict him before Herod. But if Jesus said that divorce was lawful, he would be contradicting a prophet.
