Matthew 14:14

(Verse 14.) And going out, he saw a great crowd, and he had compassion on them, and he cured their sick. In the Gospel message, the spirit is always joined with the letters, and whatever seems cold at first glance, if you touch it, it becomes warm. The Lord was in a deserted place; the crowds followed him, leaving their cities, that is, their former ways of life and the varieties of teachings.

Otherwise; The beheading of John marks the increase of that fame which Christ has among the people, as the exaltation of the Lord upon the cross marks the progress of the faith; whence John had said, He must increase, but I must decrease. (John 3:30.)

(Verse 13) And they came and told Jesus. When Jesus heard this, he withdrew from there in a boat to a deserted place by himself. They announced to the Savior the death of John the Baptist, and when he heard this, he withdrew to a deserted place. Not, as some think, out of fear of death, but sparing his enemies, lest they join one murder with another. Or deferring his own death to the day of his Passover, on which he was to be sacrificed as the Lamb (Exodus 12), and the doorposts of believers to be sprinkled with blood. Or perhaps He withdrew to give us an example of avoiding unnecessary danger, because not all have the same perseverance in enduring torments as they do in offering themselves to be tortured. For this reason, He also gives the command in another place: 'When they persecute you in this city, flee to another' (Mt. X, 23). The evangelist also elegantly does not say, 'He fled to a deserted place,' but 'He withdrew,' in order to avoid the persecutors rather than fearing them. Another interpretation: After the Jews and the king of the Jews cut off the head of the prophets and silenced the voice and speech of prophecy among them, Jesus moves to the desert, a place that the Church had not had before.

See Him on every occasion "departing," both when John was delivered up, and when he was slain, and when the Jews heard that He was making more disciples. For it is His will ordinarily to conduct things after the manner of a man, the time not yet calling Him to reveal His Godhead plainly. Wherefore also He bade His disciples "tell no man that He is the Christ;" for His will was that this should be better known after His resurrection. Wherefore upon those of the Jews that were for a time obstinate in their unbelief He was not very severe, but even disposed to be indulgent to them. And on retiring, He departs not into a city, but into a wilderness, and in a vessel, so that no man should follow. But do thou mark, I pray thee, how the disciples of John had now come to be more attached to Jesus. For it was they that told Him of the event; for indeed they have left all, and take refuge henceforth in Him. Thus, besides their calamity, His provision before made in that answer did no small good. But wherefore did He not retire before they brought Him the tidings, when yet He knew the fact before they reported it? To signify all means the reality of His economy. For not by His appearance only, but by His actions He would have this confirmed, because He knew the devil's craft, and that he would leave nothing undone to destroy this doctrine. He then for this end retires; but the multitudes not even so withdraw themselves from Him, but they follow, riveted to Him, and not even John's tragical end alarmed them. So great a thing is earnest desire, so great a thing is love; in such wise doth it overcome and dispel all dangers. Therefore they straightway also received their reward. […]

Mystically; The Word of God, on the close of the Law, entered the ship, that is, the Church; and departed into the desert, that is, leaving to walk with Israel, He passes into breasts void of Divine knowledge. The multitude learning this, follows the Lord out of the city into the desert, going, that is, from the Synagogue to the Church. The Lord sees them, and has compassion upon them, and heals all sickness and infirmity, that is, He cleanses their obstructed minds, and unbelieving hearts for the understanding of the new preaching.
