2 Kings 4:27-29

And when she came to the man of God to the hill, she caught hold of his feet. And Gehazi came near to thrust her away; but the man of God said, Let her alone: for her soul is vexed within her; and Jehovah hath hid it from me, and hath not told me. Then she said, Did I desire a son of my lord? did I not say, Do not deceive me? 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.
