Markus 6:11

6:11 If a place will not welcome you or listen to you, as you go out from there, shake the dust off ¹  your feet as a testimony against them.”

Markus 12:36

12:36 David himself, by the Holy Spirit, said,

‘The Lord said to my lord, ² 

“Sit at my right hand,

until I put your enemies under your feet.”’ ³ 

[6:11]  ¹ sn To shake the dust off represented shaking off the uncleanness from one’s feet; see Luke 10:11; Acts 13:51; 18:6. It was a sign of rejection.

[12:36]  ² sn The Lord said to my Lord. With David being the speaker, this indicates his respect for his descendant (referred to as my Lord). Jesus was arguing, as the ancient exposition assumed, that the passage is about the Lord’s anointed. The passage looks at an enthronement of this figure and a declaration of honor for him as he takes his place at the side of God. In Jerusalem, the king’s palace was located to the right of the temple to indicate this kind of relationship. Jesus was pressing the language here to get his opponents to reflect on how great Messiah is.

[12:36]  ³ sn A quotation from Ps 110:1.
