John Gill Bible Commentary

If he take him another wife,.... The father takes another wife for his son, or the son takes another wife to himself after he has betrothed and married his father's maidservant: her food, her raiment, and her duty of marriage, shall he not diminish; neither deny it her in whole, nor lessen it in part, but give her her full due of each. What is meant by the two former words is easy, and admits of no difficulty, the latter is differently interpreted. Some take it to signify no other than an "habitation" (u), that as he was to provide food and raiment for her, so an house to dwell, in; but the generality of interpreters, Jewish and Christian, understand it as we do, of the conjugal duty, the use of the marriage bed, or what the apostle calls due benevolence, Co1 7:3. The word is thought to have the signification of a fixed time for it; and the Misnic doctors (w) are very particular in assigning the set times of it for different persons; and in those countries where there were, and where there still are, plurality of wives, each had, and have their turns, see Gen 30:15. (u) "habitationem ejus", Montanus, Junius & Tremellius; so some in Aben Ezra. Vid. Pfeiffer. "dubia vexata", cent. 1. loc. 97. (w) Misn. Cetubot, c. 5. sect. 6.
