Verse 16. And they made ready the passover. This would consist in obtaining the Paschal lamb, and taking it to the temple to be sacrificed by the priests. It would then be brought to the house to be cooked; and the unleavened bread, the bitter herbs and the wine would have to be provided, and the water for purification. After all these preparations had been made, the two disciples would return to their Master.

14:12-21 Nothing could be less the result of human foresight than the events here related. But our Lord knows all things about us before they come to pass. If we admit him, he will dwell in our hearts. The Son of man goes, as it is written of him, as a lamb to the slaughter; but woe to that man by whom he is betrayed! God's permitting the sins of men, and bringing glory to himself out of them, does not oblige them to sin; nor will this be any excuse for their guilt, or lessen their punishment.And his disciples went forth,.... The two disciples, as the Arabic version has it, Peter and John, set out from Bethany to Jerusalem directly:

and came into the city; the city of Jerusalem:

and found as he had said unto them; a man bearing a pitcher of water, whom they followed to the house he went into, and addressed the master of the house, as Jesus had bid them; when he showed them an upper room, very commodious and fit for the purpose, as Christ had said; and which is a considerable proof of the prescience of Christ:

and they made ready the passover; they bought a lamb; they had it killed in the temple, according to rule; and they brought it to the house, where they were to sup, and got it roasted; and provided unleavened bread, and wine, and bitter herbs, and every thing that was proper for the feast; See Gill on Matthew 26:19.
