(19) And they went into an house.--It would be better to put a full stop after "betrayed Him," and to make this the beginning of a new sentence.

3:13-21 Christ calls whom he will; for his grace is his own. He had called the apostles to separate themselves from the crowd, and they came unto him. He now gave them power to heal sicknesses, and to cast out devils. May the Lord send forth more and more of those who have been with him, and have learned of him to preach his gospel, to be instruments in his blessed work. Those whose hearts are enlarged in the work of God, can easily bear with what is inconvenient to themselves, and will rather lose a meal than an opportunity of doing good. Those who go on with zeal in the work of God, must expect hinderances, both from the hatred of enemies, and mistaken affections of friends, and need to guard against both.And Judas Iscariot,.... So called to distinguish him from the other Judas; and is mentioned last for the following reason:

which also betrayed him; and which action of his will ever render his name infamous among men. This man, with the rest, our Lord chose to be an apostle of his, though he knew he would betray him; in order to fulfil the purposes of God, the prophecies of the Old Testament, and bring on the work of man's redemption he came into the world to perform.

And they went into an house at Capernaum; the house of Simon and Andrew, where Jesus used to be when there: they went home with him from the mountain; and from that time became his domestics, and were looked upon by him as his family, and were admitted to the greatest nearness and intimacy with him.
