Psalms 131:12

If. The promises made to the carnal posterity of David were conditional, and seem to imply, that they would forfeit them. (St. Hilary) --- But those regarding the Messias are absolute. (Calmet) --- Yet heaven is only promised to his children in the Church, if they observe God's commandments, Romans viii. 17. (Worthington) --- The kings of Juda seem not to have believed these threats; and many Christians live as if heaven required no conditions on their part. God knew what would be the event; but he speaks thus to testify their free-will, and his desire to preserve the temporal throne of David, at least till the coming fo the Messias, if the Jews had proven faithful. (Berthier)
