General Information:

God had said earlier in his word, through the prophet Isaiah, that his temple would be a house of prayer for all the nations.

Is it not written, 'My house will be called ... the nations'?

Jesus is rebuking the Jewish leaders for their misuse of the temple. This can be written as a statement. Alternate translation: "It is written in the scriptures that God said, 'I want my house to be called a house where people from all nations may pray.'" (See: rc://en/ta/man/translate/figs-rquestion)

But you have made it a den of robbers

Jesus compares the people to robbers and the temple to a robbers' den. Alternate translation: "But you are like robbers who have made my house into a robbers' den" (See: rc://en/ta/man/translate/figs-metaphor)

a den of robbers

"a cave where robbers hide"
