Isaiah 60:11

Therefore thy gates shall be open continually, they shall not be shut day nor night, since the gifts of God's mercy are dispensed in the Church without ceasing, until the end of time, that men may bring unto thee the forces of the Gentiles, large armies of heathen from every part of the world, and that their kings may be brought, as willing converts to Zion's King. Cf Luke 14:23.
