1 Peter 3:6

6 Sarah was a woman like that. She obeyed her husband, Abraham. She called him, ‘My master’. So you wives also should do what is right. Do not let anything make you afraid. Then you will be like true daughters of Sarah.

3:6Abraham was the first ancestor of the Israelite nation. He was the father of Isaac and the grandfather of Jacob. Sarah was his wife. See Genesis 11:27-23:20.
