I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be.
Greek, 'I (emphatic: "I on my part") have confidence IN х en (G1722)] the Lord (the ground of confidence) with regard to х eis (G1519)] you (2 Thessalonians 3:4), that ye will be none otherwise minded' (than what by this letter I desire you to be, Philippians 3:15) х heteros (G2087): but here allo (G243) phronein (G5426).]
But he that troubleth you (Joshua 7:25; 1 Kings 18:17-18; Acts 15:24; Galatians 1:7). The article has a selective and definitive force; the one who, for the time being, calls forth Paul's censure as the troubler (Ellicott) (Galatians 4:17).
Shall bear - as a heavy burden.
His - the judgment he deserves; namely, excommunication (Galatians 5:12): an earnest of God's judgment (Romans 2:3). Paul distinguishes the case of the seduced, misled through thoughtlessness, who, now that they are set right, he confidently hopes, will return to the right way, from that of the seducer doomed to judgment.
Whosoever he be - whether great (Galatians 1:8) or small.
