Genesis 17:17

17Then Abraham afell on his face band laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?”

Genesis 18:11-14

11Now cAbraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. 12 dSo Sarah laughed to herself, saying, eAfter I am worn out, and fmy lord is old, shall I have pleasure?” 13The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ 14 gIs anything too hard
Or wonderful
for the Lord? iAt the appointed time I will return to you, about this time next year, and Sarah shall have a son.”

Hebrews 11:11-19

11By faith jSarah herself received power to conceive, even when she was past the age, since she considered khim faithful who had promised. 12Therefore from one man, and lhim as good as dead, were born descendants mas many as the stars of heaven and as many as the innumerable grains of sand by the seashore.

13These all died in faith, nnot having received the things promised, but ohaving seen them and greeted them from afar, and phaving acknowledged that they were qstrangers and exiles on the earth. 14For people who speak thus make it clear that they are seeking a homeland. 15If they had been thinking of that land from which they had gone out, rthey would have had opportunity to return. 16But as it is, they desire a better country, that is, a heavenly one. Therefore God is not ashamed sto be called their God, for the has prepared for them a city.

17By faith uAbraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son, 18of whom it was said, vThrough Isaac shall your offspring be named.” 19 wHe considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back.
