Marie Noonan Sabin, The Gospel According to Mark, New Collegeville Bible Commentary (Liturgical Press, 2006), 32.
In chapter 2, Mark dramatizes the way that Jesus, like Wisdom, restores human beings to wholeness, both physical and spiritual. In the opening incident, he shows Jesus equating forgiveness with healing. He next shows Jesus, again like Wisdom, seeking out sinners to be his followers. In particular, he shows Jesus singling out Levi, who stands for all the Jewish religious leaders who were selling out to Rome and thus weakening Jewish faith. By calling him to be his follower, Jesus/Wisdom is implicitly calling him, and Israel in general, to turn away from worldly power and back to the wisdom of their fathers.
