Sayings to a scribe and another disciple (Luke 9:57). St. Luke introduces these sayings much later in our Lord's ministry. Both evangelists apparently borrowed from a common source, which did not specify the occasion of the utterances.
19, 20. The offer of a recognised rabbi (scribe) to become a follower of Jesus was an attractive one, especially as no influential person had yet become a disciple. Jesus, however, did not hastily accept the offer. To test the sincerity of the new convert, he required him to count the cost. He must give up all to follow Christ—home-comforts, wealth, honour, and all prospects of advancement. Like his Master, he must have no place to lay his head. Probably the scribe, like the rich young ruler, found the conditions too hard.
