Charles Ellicott Commentary 1 Corinthians 7:3

"Let the husband render unto the wife her due: and likewise also the wife unto the husband." — 1 Corinthians 7:3 (ASV)

Let the husband render unto the wife due benevolence.—Rather, Let the husband render unto the wife her due—as this is the reading of the better manuscripts. In this verse, the Apostle answers the concerns of those who were already married and who doubted whether they should continue in that state.
