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).
