John Gill Commentary Mark 6:29

"And when his disciples heard [thereof], they came and took up his corpse, and laid it in a tomb." — Mark 6:29 (ASV)

And when his disciples heard of it
That is, when the disciples of John heard of this barbarous execution of their master,

they came ;
to the prison in the castle of Machaerus,

and took up his corpse ;
the trunk of his body; for his head was carried away, to glut the revenge of Herodias;

and laid it in a tomb; (See Gill on Matthew 14:12).
