Exodus 21:10 New English Translation

¹⁰If he takes another wife,^[a] he must not diminish the first one’s food,^[b] her clothing, or her marital rights.^[c]

Exodus 21:10 tn “wife” has been supplied.
Exodus 21:10 tn The translation of “food” does not quite do justice to the Hebrew word. It is “flesh.” The issue here is that the family she was to marry into is wealthy, they ate meat. She was not just to be given the basic food the ordinary people ate, but the fine foods that this family ate.
Exodus 21:10 sn Traditional Rabbinic interpretation, affirmed in spirit by the Apostle Paul in 1 Cor 7:5, understands the term עֹנָה (ʿonah) to refer to rights to sexual relations within marriage. The term only occurs in this verse and its precise nuance is unclear. An alternate opinion is proposed by S. Paul, “Exodus 21:10, A Threefold Maintenance Clause,” JNES 28 (1969): 48-53. He suggests that the third element listed is not marital rights, but ointments, since Sumerian and Akkadian texts list food, clothing, and oil as the necessities of life. But none of the three are cognates to the words in the Hebrew list (a cognate term for “clothing” was not used) and the sequence is different than the Akkadian, so it is unlikely that it represents a shared standard legal formulation. The point is that the husband cannot play favorites and functionally demote his first wife.
