Art thou bound unto a wife? - Art thou already married? Marriage is often thus represented as a “tie,” a “bond,” etc.; see the note at Romans 7:2.
Seek not to be loosed - Seek not a “dissolution” (λύσιν lusin) of the connection, either by divorce or by a separation from each other; see the notes on 1 Corinthians 7:10-17.
Art thou loosed from a wife? - Art thou unmarried? It should have been rendered “free from” a wife; or art thou single? It does not imply of necessity that the person had been married, though it may have that meaning, and signify those who had been separated from a wife by her death. There is no necessity of supposing that Paul refers to persons who had divorced their wives. So Grotius, Schleusner, Doddridge, etc.
