Galatians 1:8
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ἀλλὰ καὶ ἐὰν ἡμεῖς ἢ ἄγγελος ἐξ οὐρανοῦ εὐαγγελίζηται ὑμῖν παρ’ ὃ εὐηγγελισάμεθα ὑμῖν, ἀνάθεμα ἔστω.
But even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be under a curse!
