Luke 20:5 Meaning and Commentary

Luke 20:5

And they reasoned with themselves
Or "they thought with themselves", as the Syriac version; or "within themselves", as the Vulgate Latin, though they did not express it; or "one with another", as the Arabic version; they took counsel together, and debated the matter among themselves, and reasoned after this manner:

saying, if we shall say from heaven;
which was what, in their own consciences, they believed to be true,

he will say, why then believed ye him not?
in what he said concerning the Messiah; which if they had, as they should, there would have been no reason for such a question they had put; (See Gill on Matthew 21:25).

Luke 20:5 In-Context

3 “I will also ask you a question,” Jesus replied. “Tell Me:

4 John’s baptism—was it from heaven, or from men?”

5 They deliberated among themselves and said, “If we say, ‘From heaven,’ He will ask, ‘Why did you not believe him?’

6 But if we say, ‘From men,’ all the people will stone us, for they are convinced that John was a prophet.”

7 So they answered that they did not know where it was from.
