'Husband's' in the Bible

-- children not born by human parents or by human desire or a husband's decision, but by God.

He who has the bride is the husband: but the husband's friend, whose place is by his side and whose ears are open to him, is full of joy because of the husband's voice: such is my joy, and it is complete.

Instantly she fell down dead at his feet, and the young men came in and found her dead. So they carried her out and buried her by her husband's side.

This accounts for the fact that if during her husband's life she lives with another man, she will be stigmatized as an adulteress; but that if her husband is dead she is no longer under the old prohibition, and even though she marries again, she is not an adulteress.
