1 Corinthians 7:27

7:27 The one bound to a wife should not seek divorce. The one released from a wife should not seek marriage. ² 

[7:18]  ¹ tn Grk “Let him not pull over the foreskin,” that is, attempt to reverse the appearance of circumcision by a surgical procedure. This was sometimes done by Hellenistic Jews to hide the embarrassment of circumcision (1 Macc 1:15; Josephus, Ant. 12.5.1 [12.241]). Cf. BDAG 380 s.v. ἐπισπάω 3.

[7:27]  ² tn Grk “should not seek a wife.”
