“Jesus said.

‘It is written,

‘My house

Shall be

A house of prayer.’

But you have made it

A den of robbers.’”

λέγων αὐτοῖς Γέγραπται Καὶ ἔσται ὁ οἶκός μου οἶκος προσευχῆς· ὑμεῖς δὲ αὐτὸν ἐποιήσατε σπήλαιον λῃστῶν.

Luke indicated that Jesus said to them (λέγων αὐτοῖς) that it was written (Γέγραπται) that my house shall be a house of prayer (Καὶ ἔσται ὁ οἶκός μου οἶκος προσευχῆς).  However, they had made it into a den or hideout of robbers or thieves (ὑμεῖς δὲ αὐτὸν ἐποιήσατε σπήλαιον λῃστῶν).  This first citation about the house of prayer is from 3^rd Isaiah, chapter 56:7, while the second citation about how they have made his Temple into a den of robbers is from Jeremiah, chapter 7:11.  These biblical citations of Jesus in the Temple can also be found in Matthew, chapter 21:13, and Mark, chapter 11:17, almost word for word.  John, chapter 2:16-17, was slightly different, since he used a citation from Psalm 69:9, where the Psalmist or David had great zeal for the house of Yahweh that he was about to construct.  Mark said that Jesus was teaching (καὶ ἐδίδασκεν).  He asked them if they knew where it was written in Scripture (καὶ ἔλεγεν αὐτοῖς Οὐ γέγραπται) that his house shall be called a house of prayer (ὅτι Ὁ οἶκός μου οἶκος προσευχῆς κληθήσεται) for all the nations (πᾶσιν τοῖς ἔθνεσιν).  Matthew and Luke did not mention all the nations.  However, the Temple functionaries were making it into a den or hideout of robbers or bandits (ὑμεῖς δὲ πεποιήκατε αὐτὸν σπήλαιον λῃστῶν).  Likewise, Matthew said that Jesus told them that it was written in Scripture (καὶ λέγει αὐτοῖς Γέγραπται) that his house shall be called a house of prayer (Ὁ οἶκός μου οἶκος προσευχῆς κληθήσεται).  However, they were making it into a den or hideout of robbers or bandits (ὑμεῖς δὲ αὐτὸν ποιεῖτε σπήλαιον λῃστῶν).  In all cases, Jesus was upset that the Jerusalem Temple house of prayer had been hijacked by a bunch of thieves and robbers.  What kind of house of prayer do you pray in?
