Genesis Chapter 12

12:1-3
Now the Lord had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will show thee:
And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.

12:11-13
And it came to pass, when he was come near to enter into Egypt, that he said unto Sarai his wife, Behold now, I know that thou art a fair woman to look upon:
Therefore it shall come to pass, when the Egyptians shall see thee, that they shall say, This is his wife: and they will kill me, but they will save thee alive.
Say, I pray thee, thou art my sister: that it may be well with me for thy sake; and my soul shall live because of thee.

12:17-19
And the Lord plagued Pharaoh and his house with great plagues because of Sarai Abram's wife.
And Pharaoh called Abram, and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?
Why saidst thou, She is my sister? so I might have taken her to me to wife: now therefore behold thy wife, take her, and go thy way.
