The Greek indicates more distinctly the simultaneousness of the entrance and the salutation: as ye are entering. Rev., as ye enter. So of the departure, as ye are going forth (ἐξερχόμενοι, Matthew 10:14).

"The very dust of a heathen country was unclean, and it defiled by contact. It was regarded like a grave, or like the putrescence of death. If a spot of heathen dust had touched an offering, it must at once be burnt. More than that, if by mischance any heathen dust had been brought into Palestine, it did not and could not mingle with that of 'the land,' but remained to the end what it had been - unclean, defiled and defiling everything to which it adhered." The apostles, therefore, were not only to leave the house or city which should refuse to receive them, "but it was to be considered and treated as if it were heathen, just as in the similar case mentioned in Matthew 18:17. All contact with such must be avoided, all trace of it shaken off" (Edersheim, "Jewish Social Life in the Days of Christ"). The symbolic act indicated that the apostles and their Lord regarded them not only as unclean, but as entirely responsible for their uncleanness. See Acts 18:6.

Cognate to the word ἀπόστολος (apostle). The I is emphatic: "It is I that send you forth."

Wise (φρόνιμοι)

So A.V. and Rev. Denoting prudence with regard to their own safety. Wyc., wary.

Harmless (ἀκέραιοι)

Lit., unmixed, unadulterated. Used of wine without water, and of metal without alloy. Hence guileless. So Luther, without falsity. Compare Romans 16:19; Philippians 2:15. They were to imitate the serpent's wariness, but not his wiliness. "The presence of the wolves demands that ye be wary; the fact that ye are my apostles (compare "I send you") demands that ye be guileless" (Dr. Morison on Matthew).

Lit., "the men," already alluded to under the term wolves.

Rev., Be not anxious. See on Matthew 6:25.

In that hour (ἐν ἐκείνῃ τῇ ὥρᾳ)

Very precise. "In that selfsame hour." Bengel remarks: "Even though not before. Many feel most strongly their spiritual power when the hour comes to impart it to others."

There is a coarse witticism in the application of the word to Christ. Jesus calls himself "the Master of the house," and the Jews apply to him the corresponding title of the Devil, Hebrews, Beelzebul, Master of the dwelling. (The phrase reappears in German, where the Devil is sometimes called Herr vom Haus. See Goethe, "Faust," sc. xxi.). Dr. Edersheim's explanation, though ingenious, seems far-fetched. He says that szebuhl, in Rabbinic language, means, not any ordinary dwelling, but specifically the temple ; so that Beelzebul would be Master of the Temple, an expression having reference to the claims of Jesus on his first purification of the temple. He then conceives a play between this word and Beelzibbul, meaning Lord of idolatrous sacrifice, and says: "The Lord of the temple was to them the chief of idolatrous worship; the representative of God, that of the worst of demons. Beelzebul was Beelzibbul. What, then, might his household expect at their hands?" ("Life and Times of Jesus").

Better Rev., proclaim. See on Matthew 4:17.

The word is a diminutive, little sparrows, and carries with it a touch of tenderness. At the present day, in the markets of Jerusalem and Jaffa, long strings of little birds, sparrows and larks, are offered for sale, trussed on long wooden skewers. Edersheim thinks that Jesus may have had reference to the two sparrows which, according to the Rabbins, were used in the ceremonial of purification from leprosy (Leviticus 14:49-54).

Shall not fall

A Rabbinic legend relates how a certain Rabbi had been for thirteen years hiding from his persecutors in a cave, where he was miraculously fed; when he observed that when the bird-catcher laid his snare, the bird escaped or was caught, according as a voice from heaven proclaimed "Mercy" or "Destruction." Arguing that if even a sparrow cannot be caught without heaven's bidding, how much more safe was the life of a son of man, he came forth.

A peculiar but very significant expression. Lit., "Confess in me." The idea is that of confessing Christ out of a state of oneness with him. "Abide in me, and being in me, confess me." It implies identification of the confessor with the confessed, and thus takes confession out of the category of mere formal or verbal acknowledgment. "Not every one that saith unto me, ' Lord! Lord!' shall enter into the kingdom of heaven." The true confessor of Christ is one whose faith rests in him. Observe that this gives great force to the corresponding clause, in which Christ places himself in a similar relation with those whom he confesses. "I will confess in him." It shall be as if I spoke abiding in him. "I in them and thou in me, that they may be perfected into one, and that the world may know that thou hast sent me, and hast loved them as thou hast loved me" (John 17:23).
