Genesis 17:17

17:17 Then Abraham bowed down with his face to the ground and laughed as he said to himself, “Can a son be born to a man who is a hundred years old? Can Sarah bear a child at the age of ninety?”

Genesis 18:11-14

18:11 Abraham and Sarah were old and advancing in years; Sarah had long since passed menopause.) 18:12 So Sarah laughed to herself, thinking, “After I am worn out will I have pleasure, especially when my husband is old too?”

18:13 The Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child when I am old?’ 18:14 Is anything impossible for the Lord? I will return to you when the season comes round again and Sarah will have a son.”

Hebrews 11:11-19

11:11 By faith, even though Sarah herself was barren and he was too old, he received the ability to procreate, because he regarded the one who had given the promise to be trustworthy. 11:12 So in fact children were fathered by one man – and this one as good as dead – like the number of stars in the sky and like the innumerable grains of sand on the seashore. 11:13 These all died in faith without receiving the things promised, but they saw them in the distance and welcomed them and acknowledged that they were strangers and foreigners on the earth. 11:14 For those who speak in such a way make it clear that they are seeking a homeland. 11:15 In fact, if they had been thinking of the land that they had left, they would have had opportunity to return. 11:16 But as it is, they aspire to a better land, that is, a heavenly one. Therefore, God is not ashamed to be called their God, for he has prepared a city for them. 11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, yet he was ready to offer up his only son. 11:18 God had told him, “Through Isaac descendants will carry on your name,” 11:19 and he reasoned that God could even raise him from the dead, and in a sense he received him back from there.
