8. Amasa went before them—Having collected some forces, he by a rapid march overtook the expedition at Gibeon, and assumed the place of commander; in which capacity, he was saluted, among others, by Joab.

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 (Lu 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.
