“But if you call yourself
On the law.
Of your relationship
Εἰ δὲ σὺ Ἰουδαῖος ἐπονομάζῃ καὶ ἐπαναπαύῃ νόμῳ καὶ καυχᾶσαι ἐν Θεῷ
However, Paul said that if you call yourself a Jew (Εἰ δὲ σὺ Ἰουδαῖος ἐπονομάζῃ), you rely on the law (καὶ ἐπαναπαύῃ νόμῳ). You boast (καὶ καυχᾶσαι) of your relationship to God (ἐν Θεῷ). Only the Pauline letters used these words ἐπονομάζῃ, that means to call by a name, a name, or named, and the word καυχᾶσαι, that means to boast, to be glorified, or proud. Paul pointed out that it was a different situation for those who were called Jews. They had the law of God and boasted or were proud about their relationship to God, as the chosen ones. They had the Mosaic law to guide them. Do you follow the Mosaic law?
