1 Korintus 3:4

3:4 For whenever someone says, “I am with Paul,” or “I am with Apollos,” are you not merely human? ¹ 

1 Korintus 7:18

7:18 Was anyone called after he had been circumcised? He should not try to undo his circumcision. ²  Was anyone called who is uncircumcised? He should not get circumcised.

1 Korintus 7:21

7:21 Were you called as a slave? ³  Do not worry about it. But if indeed you are able to be free, make the most of the opportunity.

[3:4]  ¹ tn Grk “are you not men,” i.e., (fallen) humanity without the Spirit’s influence. Here Paul does not say “walking in accordance with” as in the previous verse; he actually states the Corinthians are this. However, this is almost certainly rhetorical hyperbole.

[7:18]  ² 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.

[7:21]  ³ tn Traditionally, “servant” (KJV), though almost all modern translations render the word as “slave” here.
