Parallel
Galatians 4:17
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
They zealously affect you (note: Or, us), but not well; yea, they would exclude you, that ye might affect them.
Those people are zealous for you, but not in a good way. Instead, they want to isolate you from us, so that you may be zealous for them.
