God told Abram to leave everything and everyone behind. He said, “I will make you a great nation. I will bless you and make you famous. You will be a blessing to others. I will bless those who bless you and curse those you don’t like you.” (How does God pick his favorites?)
So Abram took Lot with him, which I guess was approved. Turns out he took Sarai and everyone else who lived with him, along with his livestock to the land of Canaan. They traveled to Shechem and set up camp beside the oak of Moreh.
God told Abram he would give the land to his descendants. Abram built and altar and dedicated it to God. Abram traveled some more, building altars along the way.
A famine struck Canaan, forcing Abram to go to Egypt. Abram told Sarai, “Look, boo. You’re very beautiful. When the Egyptians see you they will kill me to have you. Please tell them you’re my sister. Then they’ll treat me well because they like you. (Nice application of self-preservation.)
Everyone noticed her beauty. Palace officials told the pharaoh about her and she was taken to his palace. Pharaoh gave Abram gifts (servants and livestock) because of her.
But God got jealous and sent terrible plagues upon Pharaoh’s household. Pharaoh blamed Abram for not telling him that Sarai was his wife. (I don’t know how he found out.) Anyway, in the meantime, Pharaoh had taken Sarai as his wife. Sequential order be damned. He told Abram to take her back and leave.
