This narrative is at present omitted by Luke, because he had explained it on a former occasion; and for my own part, as I am unwilling to annoy my readers by writing the same thing twice, I shall handle this passage with greater brevity The allusion is to his exposition of Luke iii. 19, 20, which will be found in Harmony, vol. 1. p. 222. — Ed.

Matthew Henry Presbyterian @wholebiblehenry

We have here the story of John's martyrdom. Observe, I. The occasion of relating this story here, Mat 14:1, Mat 14:2. Here is, 1. The account brought to Herod of the miracles which Christ wrought. Herod the tetrarch or chief governor of Galilee heard of the fame of Jesus.

For Herod had laid hold on John,.... By his servants, whom he sent to apprehend him: and bound him; laid him in chains, as if he was a malefactor; and put him in prison, in the castle of Machaerus (d), for Herodias's sake; who was angry with him, had a bitter quarrel against him, and by whose instigation all this was done; who was his brother Philip's wife.
