Lukas 20:4

baptism of John--his whole ministry and mission, of which baptism was the seal.

In this chapter we have, I. Christ's answer to the chief priests' question concerning his authority (Luk 20:1-8). II. The parable of the vineyard let out to the unjust and rebellious husbandmen (Luk 20:9-19). III. Christ's answer to the question proposed to him concerning the lawfulness of paying tribute to Caesar (Luk 20:20-26). IV. His vindication of that great fundamental doctrine of the Jewish and Christian institutes - the resurrection of the dead and the future state, from the foolish cavils of the Sadducees (Luk 20:27-38). V. His puzzling the scribes with a question concerning the Messiah's being the Son of David (Luk 20:39-44). VI. The caution he gave his disciples to take heed of the scribes (Luk 20:45-47). All which passages we had before in Matthew and Mark, and therefore need not enlarge upon them here, unless on those particulars which we had not there.

20:4-6 Jesus’ question put the religious leaders in a double bind (see 20:5-6), as either answer would indict them.
