ISB ~ 2 Corinthians 11 v13

false apostles:The precise identity and mission of these agitators are unknown.

Paul provides us with only general information:(1) they were Israelites (11:22), (2) they furnished letters of recommendation for themselves (3:1), (3) they preached a foreign gospel (11:4), (4) they accepted financial support for their services (2:17), (5) they took advantage of the Corinthians (11:20), (6) they were outsiders who invaded Paul’s missionary field during his absence (10:13-18), and (7) they were severely critical of Paul (6:8; 10:2, 10). Some scholars have argued on the basis of this that the Corinthian impostors were like the Judaizers in Galatia who pressured Christians to accept circumcision and embrace the entire ritual law of the Old Covenant. In this case, they may have come from Judea to collect money (taxes) for the Jerusalem Temple.
