'Husband's' in the Bible

She also said, "Who would have told Abraham that Sarah would nurse sons? Yet I have given birth to a son in my husband's old age!"

This is the law in cases of jealousy when a woman defiles herself while under her husband's authority:

If, while she had been living in her late or former husband's house, she makes a vow or a promise that binds her with an oath,

But if the man does not want to marry his brother's widow, then she must go to the elders at the city gate and declare, "My husband's brother refuses to perform the duty of a brother-in-law in order to preserve the name of his brother in Israel. He is not willing to perform the duty of a brother-in-law.'
