以利沙對基哈西說：«你要束上腰，手裡拿著我的杖去。若遇見人，不要向他問安；若有人向你問安，也不要回答他。要把我的杖放在孩子的臉上。»
Tze'enah Ure'enah
“He said to Gehazi: gird up your loins, etc.” [4:29]. Elisha said to his servant Gehazi. Gird your loins and take my staff in your hand and when you will meet a person, do not greet them. Whoever will greet you, do not respond, and put my staff on the child’s face. He also commanded him that he should not tarry on the way. The Midrash writes that the staff was a joke in Gehazi’s eyes. He said: is it possible that the staff will make a dead person come to life. This is what Gehazi said to every person that he encountered and said: do you believe that the staff brings to life?6Pirke de Rabbi Eliezer, chap. 33.
Rashi
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.24Geichazi took his mission very lightly and considered it a joke. He was therefore unsuccessful in his mission. Radak When anyone asked him [where he was going], he responded, “My master sent me to revive the dead.”25Alternatively, Elisha initially thought that the boy had merely fainted and therefore his personal presence would not be necessary.—Malbim
