That is not From The Navi, Isaiah.
It is from the Torah, Bereshit 12:3 ( Genesis) , Parshah Lech Lecha,
It is HaShem promising Abraham the land of Yisrael, and that the Jewish people will become a mighty nation, that all nations will be Blessed in her, and that G-D will Bless those that Bless Israel, and Curse Those who Curse Israel.
Here is the correct, authentic Rabbinic translation of the Parshah from the original Hebrew of the Torah:
1. And the Lord said to Abram, “Go forth from your land and from your birthplace and from your father’s house, to the land that I will show you.
2. And I will make you into a great nation, and I will bless you, and I will aggrandize your name, and [you shall] be a blessing.
3. And I will bless those who bless you, and the one who curses you I will curse, and all the families of the earth shall be blessed in you.”
4. And Abram went, as the Lord had spoken to him, and Lot went with him, and Abram was seventy five years old when he left Haran.
5. And Abram took Sarai his wife and Lot his brother’s son, and all their possessions that they had acquired, and the souls they had acquired in Haran, and they went to go to the land of Canaan, and they came to the land of Canaan.
6. And Abram passed through the land, until the place of Shechem, until the plain of Moreh, and the Canaanites were then in the land.
7. And the Lord appeared to Abram, and He said, “To your seed I will give this land,” and there he built an altar to the Lord, Who had appeared to him.
8. And he moved from there to the mountain, east of Beth el, and he pitched his tent; Beth el was to the west and Ai was to the east, and there he built an altar to the Lord, and he called in the name of the Lord.
9. And Abram traveled, continually traveling southward.
10. And there was a famine in the land, and Abram descended to Egypt to sojourn there because the famine was severe in the land.
11. Now it came to pass when he drew near to come to Egypt, that he said to Sarai his wife, “Behold now I know that you are a woman of fair appearance.
12. And it will come to pass when the Egyptians see you, that they will say, ‘This is his wife,’ and they will slay me and let you live.
13. Please say [that] you are my sister, in order that it go well with me because of you, and that my soul may live because of you.”
14. And it came to pass when Abram came to Egypt, that the Egyptians saw the woman, that she was very pretty.
15. And Pharaoh’s princes saw her, and they praised her to Pharaoh, and the woman was taken to the house of Pharaoh.
16. And he benefited Abram for her sake, and he had flocks and cattle and he donkeys and men servants and maid servants, and she donkeys and camels.
17. And the Lord plagued Pharaoh [with] great plagues as well as his household, on account of Sarai, Abram’s wife.
18. And Pharaoh summoned Abram, and he said, “What is this that you have done to me? Why did you not tell me that she was your wife?
19. Why did you say, ‘She is my sister,’ so that I took her to myself for a wife? And now, here is your wife; take [her] and go.”
20. And Pharaoh commanded men on his behalf, and they escorted him and his wife and all that was his.
So the Pharoah was boffing Abraham’s hot wife because Abraham told her to lie that she wasn’t his wife, but rather his sister? And he basically gave her away because he was scared of getting killed if they knew she was his wife? Wow.
