17 And he taught, saying unto them, Is it not written, My house shall be called of all  nations the house of prayer? but ye have made it a den of thieves.
17 And as he taught them, he said, "Is it not written: 'My house will be called a house of prayer for all nations'
17 And he was teaching them and saying to them, "Is it not written, 'My house shall be called a house of prayer for all the nations'? But you have made it a den of robbers."
17 And then he taught them, quoting this text: My house was designated a house of prayer for the nations; You've turned it into a hangout for thieves.
17 Then He taught, saying to them, "Is it not written, 'My house shall be called a house of prayer for all nations'? But you have made it a 'den of thieves.' "
17 He said to them, "The Scriptures declare, 'My Temple will be called a house of prayer for all nations,' but you have turned it into a den of thieves."
Matthew Henry's Commentary on Mark 11:17
Commentary on Mark 11:12-18
(Read Mark 11:12-18)
Christ looked to find some fruit, for the time of gathering figs, though it was near, was not yet come; but he found none. He made this fig-tree an example, not to the trees, but to the men of that generation. It was a figure of the doom upon the Jewish church, to which he came seeking fruit, but found none. Christ went to the temple, and began to reform the abuses in its courts, to show that when the Redeemer came to Zion, it was to turn away ungodliness from Jacob. The scribes and the chief priests sought, not how they might make their peace with him, but how they might destroy him. A desperate attempt, which they could not but fear was fighting against God.
