Matthew Poole and continuators on Galatians 6:13

13 For neither they themselves who are circumcised keep the law , but desire to have you circumcised, that they may glory in your Flesh .

In this the Hypocrisie of your false Teachers discovereth its self, that whereas by their being circumcised, they had declared themselves Debtors to the whole Law, and under an obligation entirely to keep it if they would be saved; yet they themselves did not keep it, only were very zealous for this one thing, not out of any love they had to the Law.

But that they might Glory of you, as their Converts being by them perswaded to be circumcised.
