Romans 2:17

He now comes to deal more particularly and expressly with the Jews, reciting their privileges, in which they trusted, and of which they boasted; and shows, that notwithstanding them, they stood in as much need of the righteousness of God as the Gentiles did. Thou; he speaks in the singular number, that every one might make the readier application of what he said. Art called a Jew; so called from Judah; as of old, Hebrews from Heber, and Israelites from Israel: the title was honourable in those days, and imported a confessor or worshipper of one God. Thou art so called, but art not so indeed: see Romans 2:28, and Revelation 2:9. Restest in the law; puttest thy trust in it. Makest thy boast of God; that he is thy God, and in covenant with thee; and that thou hast a peculiar interest in him: see 1 Thessalonians 8:41. The phrase seems to be borrowed from Isaiah 45:25.
