Discovery Box1 Corinthians 7:18-20 
Context7:18 Was anyone called after he had been circumcised? He should not try to undo his circumcision. 1 Was anyone called who is uncircumcised? He should not get circumcised. 7:19 Circumcision is nothing and uncircumcision is nothing. Instead, keeping God’s commandments is what counts. 7:20 Let each one remain in that situation in life 2 in which he was called.
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.
2 tn Grk “in the calling.” “Calling” in Paul is God’s work of drawing people to faith in Christ. As in 1:26, calling here stands by metonymy for a person’s circumstances when he becomes a Christian.
