Matthew Poole and continuators on 1 Corinthians 7:3

3 Let the husband render unto the wife due benevolence : and likewise also the wife unto the husband .

The word translated due benevolence, signifieth due good will or kindness, but from v. 5. it appeareth what the Apostle meaneth; Moses, Exod. 21.10. calleth it, the duty of marriage, both of them using a modest term in expressing the conjugal act, as we shall observe the Scripture always doing, when there is occasion to mention what men of profane hearts are ready to make a scoff at.

The Apostle maketh this the mutual duty both of husband and wife under due circumstances, therefore useth the word render, which implieth the thing required to be an act of justice.
