От Матфея 17:4

HEALING OF A DEMONIAC BOY--SECOND EXPLICIT ANNOUNCEMENT BY OUR LORD OF HIS APPROACHING DEATH AND RESURRECTION. ( = Mark 9:14-32; Luk 9:37-45). (Mat 17:14-23) And while they abode in Galilee, Jesus said unto them--Mark (Mar 9:30), as usual, is very precise here: "And they departed thence"--that is, from the scene of the last miracle--"and passed through Galilee; and He would not that any man should know it." So this was not a preaching, but a private, journey through Galilee. Indeed, His public ministry in Galilee was now all but concluded. Though He sent out the Seventy after this to preach and heal, He Himself was little more in public there, and He was soon to bid it a final adieu. Till this hour arrived, He was chiefly occupied with the Twelve, preparing them for the coming events. The Son of man shall be betrayed into the hands of men . . . And they were exceeding sorry--Though the shock would not be so great as at the first announcement (Mat 16:21-22), their "sorrow" would not be the less, but probably the greater, the deeper the intelligence went down into their hearts, and a new wave dashing upon them by this repetition of the heavy tidings. Accordingly, Luke (Luk 9:43-44), connecting it with the scene of the miracle just recorded, and the teaching which arose out of it--or possibly with all His recent teaching--says our Lord forewarned the Twelve that they would soon stand in need of all that teaching: "But while they wondered every one at all things which Jesus did, He said unto His disciples, Let these sayings sink down into your ears; for the Son of man shall be delivered," &c.: "Be not carried off your feet by the grandeur you have lately seen in Me, but remember what I have told you, and now tell you again, that that Sun in whose beams ye now rejoice is soo…

In this chapter we have, I. Christ in his pomp and glory transfigured (Mat 17:1-13). II. Christ in his power and grace, casting the devil out of a child (Mat 17:14-21). And, III. Christ in his poverty and great humiliation, 1. Foretelling his own sufferings (Mat 17:22, Mat 17:23). 2. Paying tribute (Mat 17:24-27). So that here is Christ, the Brightness of his Father's glory, by himself purging our sins, paying our debts, and destroying for us him that had the power of death, that is, the devil. Thus were the several indications of Christ's gracious intentions admirable interwoven.

17:4 three shelters as memorials: Peter probably thought that the Kingdom was about to be ushered in with full glory (cp. Acts 1:6), and he desired to memorialize the moment.
