Matthew 21 verse 13 says,And said unto them,it is written,My house shall be called the house of prayer,but ye have made it a den of thieves. In this verse the lord jesus christ said "it is written"so christ is quoting from a former scripture where it is written that God said my house shall be called the house of prayer. Whenever he says it is written, we expect and we know that he is citing a scripture, and inspired scripture. The lord got the word it is written from the book of isaiah chapter 36 verse 7 which says,even them will I bring to my holy mountain,and make them joyful in my house of prayer, their burnt offerings and their sacrifices shall be called a house of prayer for all people.
There are people who will turn the house of the prayer of God into the den of robbers or thieves Jeremiah 7 verse 11 says,is this house, which is called by my name,become a den of robbers in my eyes? Behold, even I have seen it,saith the lord. Even before it was said by the lord jesus christ it was prophesied by jesus in jeremiah, so when he said in Matthew 21 verse 13 and said unto them,it is written, My house shall be called the house of prayer,but ye have made it a den of thieves. It did not come from jesus, remember the lord jesus christ sent by the father to preach to word of the father that's why there are pronouncement of the father in the old testament that where repeated by the lord.
John 12 verse 49 says,For I have spoken of myself,but the father which sent me,he gave me the commandment, what i should say,and what I should speak. Verse 50 says, and I know his commandment is life everlasting, whatsoever I speak therefore, even as the father said unto me,so I speak. The house of prayer in Jerusalem which is the den of thieves is the temple turned into a business place of the changes, those that are selling dogs and lambs etc because the Jews are offering these things to the altar if they want to offer there are already peddlers there of these things that they are offering that's why those businessmen in the time of jesus christ made the house of prayer a den of thieves.
Why it's not a house of prayer anymore In the first century particularly in the time of the lord jesus christ.he said to the apostles that the temple will be totally destroyed,which is the house of prayer. Jesus said to the apostle that particular temple which is called the house prayer will be destroyed. He said that in advance to the apostle.
