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 And He answered and said unto them, "I will also ask you one thing, and answer Me:

4 The baptism of John -- was it from Heaven, or of men?"

5 And they reasoned among themselves, saying, "If we shall say `From Heaven,' he will say, `Why then have ye not believed him?'

6 But if we say, `Of men,' all the people will stone us, for they are persuaded that John was a prophet."

7 And they answered that they could not tell from whence it was.
