To declare the name of the Lord in Zion,.... That is, that the prisoners and persons appointed to death, being loosed, might declare, in the church, what great things the Lord has done for them; and so speak well of his wisdom, power, grace, and goodness, in their deliverance; profess his name, and confess him before men, and express a value for his name, and show forth the honour of it, and seek his glory: and his praise in Jerusalem; the Gospel church state, the same with Zion; when it shall be the praise of the whole earth; then and there will those, that are delivered from the antichristian yoke, praise the Lord, sing the song of Moses and the Lamb, and glorify God for all that he has done for them.
