'Wife' in the Bible

Plead earnestly with your mother (for she is not my wife, and I am not her husband), so that she might put an end to her adulterous lifestyle, and turn away from her sexually immoral behavior.

The Lord said to me, "Go, show love to your wife again, even though she loves another man and continually commits adultery. Likewise, the Lord loves the Israelites although they turn to other gods and love to offer raisin cakes to idols."

Jacob fled to the country of Aram, then Israel worked to acquire a wife; he tended sheep to pay for her.
