"Good zeal draws one onto good paths, but evil zeal turns one away from them" (Chrysostom).
So they too are zealous, but without understanding. What labors they undertake to gain proselytes! But if they happen to gain them, they bring them not blessing, but final destruction, as the Savior said (cf. Mt 23:15).
Judaism was the one true faith before the coming of the Lord. After His coming, it is opposed to God and destructive, and those who follow it are sons of Gehenna.

I seek nothing that is yours, but you yourselves, and not for myself, but for you, that you may be saved.
Look into this, then, and you will see where the truth is.
At this reminder of the zeal of the false teachers, that the Galatians should be zealous for them, there came to the holy Apostle's mind the image of true zeal for the Christian faith and life.
The Galatians had shown this zeal in his presence. Remembering this, he speaks to them as though saying: I know that you were zealous for the Christian truth, in which alone all our good lies. But:
