When nearly precise rabbinic parallels to stories and sayings in the Gospels exist, it may indicate that the Gospels are preserving traditions of the early Jesus movement and, perhaps, the historical Jesus.
Like other sages of his time, Jesus demanded his disciples’ total commitment. They were to put the “kingdom of Heaven” (Jesus’ band of full-time disciples) before all else. They were to “hate,” that is, put second, father, mother, wife, children, brothers, sisters, and themselves, as well (Luke 14:26). Following Jesus to learn Torah from him was to take precedence over every other endeavor.
