What does 2 Kings 4:29 mean?

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

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

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

Then he said to Gehazi, Make yourself ready, and take my stick in your hand, and go: if you come across anyone on the way, give him no blessing, and if anyone gives you a blessing, give him no answer. And put my stick on the child's face.

And he saith to Gehazi, `Gird up thy loins, and take my staff in thy hand, and go; when thou dost meet a man, thou dost not salute him; and when a man doth salute thee, thou dost not answer him; and thou hast laid my staff on the face of the youth.'

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.

And he said to Gehazi, Gird up thy loins, and take my staff in thy hand, and go thy way. If thou meet any man, salute him not, and if any salute thee, answer him not again; and lay my staff upon the face of the lad.
