Markus 9:42

9:42 “If anyone causes one of these little ones who believe in me to sin, it would be better for him to have a huge millstone ¹  tied around his neck and to be thrown into the sea.

Markus 14:22

The Lord’s Supper

14:22 While they were eating, he took bread, and after giving thanks he broke it, gave it to them, and said, “Take it. This is my body.”

[9:42]  ¹ tn Grk “the millstone of a donkey.” This refers to a large flat stone turned by a donkey in the process of grinding grain (BDAG 661 s.v. μύλος 2; L&N 7.68-69). The same term is used in the parallel account in Matt 18:6.

[9:42]  sn The punishment of drowning with a heavy weight attached is extremely gruesome and reflects Jesus’ views concerning those who cause others who believe in him to sin.
