C. F. Keil and Franz Delitzsch on 2 Kings 4:14-16

2Ki 4:14-16

When Elisha conversed with Gehazi still further on the matter, the latter said: “But she has no son, and her husband is old.” Elisha then had her called again, and told her when she had entered the door: “At this time a year hence (חיּה כּעת, lit., at the time when it revives again; see at Gen 18:10) thou wilt embrace a son.” The same favour was to be granted to the Shunammite as that which Sarah had received in her old age, that she might learn that the God of Abraham still ruled in and for Israel. She replied: “No, my lord, thou man of God,” אל־תּכזּב, I do not excite in thy servant any deceptive hopes.
