2 Kings 4:29

If thou meet any man, salute him not. — An injunction of utmost haste. (Comp. the similar words of our Saviour, Luke 10:4.) A short greeting might end in a long halt. “Orientals lose much time in tedious salutations” (Keil).

Lay my staff upon the face of the child. — It seems to be implied that if the mother had had faith this would have sufficed for raising the child. (Comp. 2 Kings 2:8; Acts 19:12.) Keil supposes that the prophet foresaw the failure of this expedient, and intended by it to teach the Shunammitess and his followers generally that the power of working miracles was not magically inherent in himself or in his staff, as they might imagine, but only in Jehovah, who granted the temporary use of that power to faith and prayer. In other words, Elisha was seeking to lift the minds of his disciples to higher and more spiritual conceptions of the prophetic office. But this seems doubtful.
