'Adulteress' in the Bible

‘The man who commits adultery with another’s wife, even his neighbor’s wife, the adulterer and the adulteress shall most certainly be put to death.

For on account of a prostitute one is reduced to a piece of bread [to be eaten up],And the immoral woman hunts [with a hook] the precious life [of a man].

Then the Lord said to me, “Go again, love a woman (Gomer) who is beloved by her husband and yet is an adulteress, even as the Lord loves the children of Israel, though they turn to other gods and love the raisin cakes [used in the feasts in pagan worship].”

Accordingly, she will be designated as an adulteress if she unites herself to another man while her husband is alive. But if her husband dies, she is free from the law [regarding marriage], so that she is not an adulteress if she marries another man.
