John Owen: "It must be observed, that the great honour and privilege of the Judaical church-state, whereon all particular advantages did depend, was their coming unto and station at mount Sinai, at the giving of the law. There were they taken into covenant with God, to be his peculiar people above all the world; there were they formed into a national church; there had they all the privileges of divine worship committed unto them. Hereon theirs was the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises, as the apostle speaks (Rom. 9:4). This is that glory which they boast of unto this day, and whereon they rely in their unbelief and rejection of the gospel" (Hebrews, vol. 7, pp. 306-307)
