Perempuan itu pun mengandung dan melahirkan seorang anak laki-laki pada waktu seperti itu tahun berikutnya, seperti yang telah dikatakan Elisa kepadanya.

[4] Another interpretation: "And the Lord visited Sarah as He had said, and the Lord did unto Sarah as He had spoken. And the children of Israel prevailed not against him that day, and so on (1 Samuel 15:29). The Lord said, "I am not a man that I should lie," yet Elisha was made of flesh and blood because the Shunammite woman fed him, as it is said, "And she prevailed upon him to eat bread" (2 Kings 4:8). The Lord said to her at this appointed time, "I will certainly return to you at this time next year, and behold, Sarah your wife will have a son" (Genesis 18:10). And it came to pass. As it is said, "And the woman conceived and bore a son at this appointed time" (Genesis 21:2). How much more so did I say to Abraham about this appointed time, "I will surely return to you" (Genesis 18:10), and now Sarah your wife has borne you a son." (Genesis 21:2) Therefore, Balaam said, "God is not a man that He should lie," but what is written? "And Sarah conceived and bore a son to Abraham in his old age" (Genesis 21:2). David said, "For He spoke and it was done; He commanded and it stood fast" (Psalms 33:9).

What did Elisha say to the Shunamite woman? “At this very time next year, at this very time, you will embrace a son” (II Kings 4:16). She said to him: ‘“No, my lord, man of God, do not deceive your maidservant” (II Kings 4:16). Those angels who brought the tidings to Sarah said to her: “At the prescribed time, I will return to you; at this very time next year, Sarah will have a son” (Genesis 18:14). [Why, then, do you [Elisha] not likewise promise that you will return?]’ He said to her: ‘Those angels knew that they live and endure forever, so they said: “At the time, I will return to you.” But, I, who am flesh and blood, alive today and dead tomorrow, [say to you:] whether I am alive or dead, “at this very time, you will embrace a son.”’ What is written there? “The woman conceived and bore a son at that time the next year, at that very time that Elisha had spoken to her” (II Kings 4:17). If the words of flesh and blood are fulfilled, will the words of the Holy One blessed be He not be fulfilled? “The Lord remembered Sarah as He had said…”
