Hebrews 10:35—11:1
So don’t throw away your confidence, which has a great reward. For you need endurance, so that after you have done God’s will, you may receive what was promised.

For yet in a very little while,
the Coming One will come and not delay.
But my righteous one will live by faith;
and if he draws back,
I have no pleasure in him.

But we are not those who draw back and are destroyed, but those who have faith and are saved.

Now faith is the reality of what is hoped for, the proof of what is not seen.

Hebrews 11:8-10
By faith Abraham, when he was called, obeyed and set out for a place that he was going to receive as an inheritance. He went out, even though he did not know where he was going. By faith he stayed as a foreigner in the land of promise, living in tents as did Isaac and Jacob, coheirs of the same promise. For he was looking forward to the city that has foundations, whose architect and builder is God.

Hebrews 11:17-19
By faith Abraham, when God tested him, offered Isaac as a sacrifice. He who had embraced the promises was about to sacrifice his one and only son,  even though God had said to him, “It is through Isaac that your offspring will be reckoned.” Abraham reasoned that God could even raise the dead, and so in a manner of speaking he did receive Isaac back from death.

Genesis 12:11-13
When he was about to enter Egypt, he said to his wife, Sarai, “Look, I know what a beautiful woman you are. When the Egyptians see you, they will say, ‘This is his wife.’ They will kill me but let you live. Please say you’re my sister so it will go well for me because of you, and my life will be spared on your account."

Genesis 16:1-2
Abram’s wife, Sarai, had not borne any children for him, but she owned an Egyptian slave named Hagar. Sarai said to Abram, “Since the Lord has prevented me from bearing children, go to my slave; perhaps through her I can build a family.” And Abram agreed to what Sarai said.
