2 Kings 4:29 Douay-Rheims

Then he said to Giezi: Gird up thy loins, and take my staff in thy hand, and go. If any man meet thee, salute him not: and if any man salute thee, answer him not: and lay my staff upon the face of the child.

“There is another representation of the same truth: Elisha's action in first dispatching his servant with his staff to raise the dead child. The son of the woman who had given Elisha hospitality had died; the news was brought to Elisha, and he sent his servant with the staff. "Go," he told him, "lay the staff on the dead child." Was the prophet unsure what to do? The servant went on ahead and placed the staff on the corpse; but the dead child did not revive. "If a law capable of giving life had been granted to us, then of course righteousness would have been obtainable through the law." The law sent through a servant did not bring life. But Elisha, who had sent his staff with his servant, was to follow later himself and bring the child to life. After hearing that the child had not revived, Elisha came in person; he was a type of our Lord, who had sent his servant ahead of him with a staff that represents the Law. He came to the dead child lying there and placed his body over him. But the dead person was an infant and Elisha a grown man, so he contracted his adult stature and somehow curtailed it, making himself like a child so that he matched the corpse in size. The dead child arose when the living man had fitted himself to him; the Lord accomplished what the staff had failed to do; grace achieved what the Law could not.”

“Do not greet him. Do not inquire about his welfare. All this [was done] to discourage conversation, where one might ask him, “Where are you going?” and he would say, “To revive the dead.” It is not respectful for the miracle when the maker brags about it. But, he did not obey. When anyone asked him [where he was going], he responded, “My master sent me to revive the dead.””

“Then he said to Gehazi, gird up thy loins,.... His loose and long garments about him, that he might make quicker dispatch in travelling: and take my staff in thine hand, and go thy way; not for the sake of travelling with it, but for an end after mentioned: if thou meet any man, salute him not; and if any salute thee, answer him not again; that so no time may be lost: and lay my staff upon the face of the child; he not intending when he said this to go himself, but at the time, as near as he could, when this action was performed, would pray to God to restore life to the child; for he could not imagine that by this bare action it could be done.”

“Salute him not - Make all the haste thou possibly canst, and lay my staff on the face of the child; he probably thought that it might be a case of mere suspended animation or a swoon, and that laying the staff on the face of the child might act as a stimulus to excite the animal motions.”

“Salute him not. He that is sent to raise to life the sinner spiritually dead, must not suffer himself to be called off, or diverted from his enterprise, by the salutations or ceremonies of the world. (Challoner) — So must the preachers of the gospel diligently fulfil their important office, Luke x. 4. (St. Gregory, hom. 17.) Urbanity is not reprehended; but no human transaction ought to impede what is divine. (St. Ambrose, ibid.[Luke x. 4.?]) In ancient comedies, slaves are always represented in a hurry. The Jews will not salute any person when they are going to their synagogues, for fear of being distracted in their devotions. (Calmet) — Eliseus requires the utmost expedition, that the favour might be the greater, Qui cito dat, bis dat. (Menochius) — He would also prevent his servant from telling any one what he was about, that he might not be touched with vanity, and thus hinder the miracle, which some think was nevertheless the case. (R. Salomon) (Theodoret, q. 17.) (Tirinus)”

“take my staff . . . and lay . . . upon the face of the child--The staff was probably an official rod of a certain form and size. Necromancers used to send their staff with orders to the messengers to let it come in contact with nothing by the way that might dissipate or destroy the virtue imparted to it. Some have thought that Elisha himself entertained similar ideas, and was under an impression that the actual application of his staff would serve as well as the touch of his hand. But this is an imputation dishonorable to the character of the prophet. He wished to teach the Shunammite, who obviously placed too great dependence upon him, a memorable lesson to look to God. By sending his servant forward to lay his staff on the child, he raised [the Shunammite's] expectations, but, at the same time, taught her that his own help was unavailing--"there was neither voice, nor hearing." The command, to salute no man by the way, showed the urgency of the mission, not simply as requiring the avoidance of the tedious and unnecessary greetings so common in the East (Luk 10:1), but the exercise of faith and prayer. The act of Gehazi was allowed to fail, in order to free the Shunammite, and the people of Israel at large, of the superstitious notion of supposing a miraculous virtue resided in any person, or in any rod, and to prove that it was only through earnest prayer and faith in the power of God and for His glory that this and every miracle was to be performed.”
