Charles Spurgeon Commentary 2 Kings 4:29-30

"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. And the mother of the child said, As Jehovah liveth, and as thy soul liveth, I will not leave thee. And he arose, and followed her." — 2 Kings 4:29-30 (ASV)

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. And the mother of the child said, As the LORD liveth, and as thy soul liveth, I will not leave thee.

She did not believe in Gehazi, nor in the staff, and in this she was a wise woman. God would not bless the prophet's staff for the child's restoration, lest relic worship should spring up among the Israelites, or lest they should begin to attach some value to outward signs.
