the young married woman of a household: a bride toward her husband, a daughter-in-law toward his parents
Hebrew uses one word for the woman a marriage brings into a family, and it names her by whichever bond is in view. Face her toward her new husband and the word means bride, the young wife at and around her wedding. Face her toward his father and mother and the same word means daughter-in-law. English has to pick one label or the other, but the Hebrew keeps both in a single term, because to the ancient household they were one person: the woman who has just joined it by marriage.
In that world a son did not leave to start a separate home. His wife moved into his father's house, and from that moment she was at once a bride to him and a daughter-in-law to his parents. So the two meanings are not two different words that happen to sound alike. They are one social role seen from two sides, and which side the text shows depends almost entirely on the kind of writing. Poets and prophets, picturing wedding joy, call her the bride. Law and narrative, tracing a family line or protecting a household, call her the daughter-in-law.
That is why the word can glow in one book and read like a legal term in another. In the Song of Songs and in Isaiah, Jeremiah, and Joel she is the bride, adorned and rejoiced over. In Genesis, Leviticus, and Ruth she is the wife of a son, marking Tamar and Ruth and others as members of the family they married into. Micah even sets the daughter-in-law against her mother-in-law to picture a home torn apart. The shared thread under every use is the same: the woman received into a household through marriage.
Nuances
Whether calling the woman "bride" in the Song of Songs marks an actual wedding or is a term of endearment for a beloved who is not yet married.
- majorityA term of endearment and aspiration: the lovers are not portrayed as married, and "bride" voices hoped-for intimacy rather than a wedding-day status.; M. V.
