ISB ~ Galatians 1 v7

some who trouble you:The Judaizers, who labored to bring the Galatians under the yoke of circumcision and other burdensome laws of the Old Covenant (6:12-13). In doing so, they promoted a false gospel that implicitly denied the sufficiency of Christ’s death for our salvation (2:21). Although our knowledge about these troublemakers is fragmentary, they seem to share the outlook and aims of Jewish traditionalists from Judea (Acts 15:1-5; 21:20-21).
