Then Abraham fell on his face and laughed, and said in his heart, “Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a child?”
So Sarah laughed to herself [when she heard the Lord’s words], saying, “After I have become old, shall I have pleasure and delight, my lord (husband) being also old?” [1 Pet 3:6]
Then the royal officer on whose arm the king leaned answered the man of God and said, “If the Lord should make windows in heaven [for the rain], could this thing take place?” Elisha said, “Behold, you will see it with your own eyes, but [because you doubt] you will not eat of it.”
Without becoming weak in faith he considered his own body, now as good as dead [for producing children] since he was about a hundred years old, and [he considered] the deadness of Sarah’s womb. [Gen 17:17; 18:11]
