Markus 14:20

14:20 He said to them, “It is one of the twelve, one who dips his hand ¹  with me into the bowl. ² 

Markus 16:19

16:19 After the Lord Jesus had spoken to them, he was taken up into heaven and sat down at the right hand of God.

[14:20]  ¹ tn Grk “one who dips with me.” The phrase “his hand” has been supplied in the translation for clarity.

[14:20]  ² sn One who dips with me in the bowl. The point of Jesus’ comment here is not to identify the specific individual per se, but to indicate that it is one who was close to him – somebody whom no one would suspect. His comment serves to heighten the treachery of Judas’ betrayal.
