S – He was teaching them: “Is it not written, My house will be called a house of prayer for all nations? But you have made it a den of thieves!”^, 

 Mark 11:17 CSB

O – Jesus just finished throwing out the “money changers” out of the Temple from the court of the Gentiles. 

Commentary: 

Jesus’ daring action captured peoples’ attention and He taught (lit., “began teaching”) them about God’s purpose for the temple. Using a question expecting a positive answer, He appealed to Old Testament authority for His action (quoting Isa. 56:7b verbatim).

Only Mark extended the quotation from Isaiah to include the words for all nations. God desired that both Gentiles and Jews use the temple as a place of worship (cf. John 12:20). This was especially relevant to Mark’s readers in Rome.

By contrast, you (emphatic), the insensitive Jews, have made it, the court of the Gentiles, a den of robbers. It was a refuge for fraudulent traders (cf. Jer. 7:11) instead of a house of prayer

“Mark,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

O – Even in his anger, Jesus is laying more foundation for God’s plan for Jews and Gentiles to worship together.  Such a great detail.

R- Lord, thank you for being so Big, and yet you are intimate in the details of my life.  Also, continue to value all people, even those who are not like me.
