Mark 10-12 describes Jesus' teachings on marriage, divorce, humility, and serving others. Jesus heals blind Bartimaeus, enters Jerusalem, and cleanses the temple. He engages in debates with religious leaders about authority, taxes, resurrection, and God's greatest commandment. Jesus warns about hypocritical religious leaders and praises a poor widow's small donation to the temple. Throughout, Jesus prepares his disciples for his coming passion, death, and resurrection.
