2 Kings 4:27-29

And when she came to the man of God to the hill, she caught him by the feet: but Gehazi came near to thrust her away. And the man of God said, Let her alone; for her soul is vexed within her: and the LORD 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 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.
