Knowing that he was a just man and an Holy - A holy, pious, upright, honest man - a man who would not be afraid of him, or afraid to speak his real sentiments.

And observed him - Margin, "kept him, or saved him." This does not mean that he "observed" or obeyed his teachings, but that he kept him in safe custody in order to preserve him from the machinations of Herodias. He was willing to show his respect for John, and to secure him from danger, and even to do "many things" which might indicate respect for him - at least, to do so much as to guard him from his enemies.

And did many things - But he did not do the thing which was demanded of him - to break off from his sins. He attempted to make a compromise with his conscience. He still loved his sins, and did "other" things which he supposed might be accepted in the place of putting away, as he ought, the wife of his brother - the polluted and adulterous woman with whom he lived. Perhaps he treated John kindly, or spoke well of him, or aided him in his wants, and attempted in this way to silence his rebukes and destroy his faithfulness. This was probably before John was imprisoned. So sinners often treat ministers kindly, and do much to make them comfortable, and hear them gladly, while they are still unwilling to do the thing which is demanded of them - to repent and believe the gospel. They expect that their kind attentions will be accepted in the place of what God demands - repentance and the forsaking of their sins.

they came and took up his corpse, and laid it in a tomb—"and went and told Jesus" (Mt 14:12). If these disciples had, up to this time, stood apart from Him, as adherents of John (Mt 11:2), perhaps they now came to Jesus, not without some secret reflection on Him for His seeming neglect of their master; but perhaps, too, as orphans, to cast in their lot henceforth with the Lord's disciples. How Jesus felt, or what He said, on receiving this intelligence, is not recorded; but He of whom it was said, as He stood by the grave of His friend Lazarus, "Jesus wept," was not likely to receive such intelligence without deep emotion. And one reason why He might not be unwilling that a small body of John's disciples should cling to him to the last, might be to provide some attached friends who should do for his precious body, on a small scale, what was afterwards to be done for His own.

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.
