II. How they must praise the Lord. 1. By prayer: Call upon his name. As giving thanks for former mercy is a decent way of begging further mercy, so begging further mercy is graciously accepted as a thankful acknowledgment of the mercies we have received. In calling upon God's name we give unto him some of the glory that is due to his name as our powerful and bountiful benefactor. 2. By preaching and writing. We must not only speak to God, but speak to others concerning him, not only call upon his name, but (as the margin reads it) proclaim his name; let others know something more from us than they did before concerning God, and those things whereby he has made himself known. Declare his doings, his counsels (so some read it); the work of redemption is according to the counsel of his will, and in that and other wonderful works that he has done we must take notice of his thoughts which are to us-ward, Ps. xl. 5. Declare these among the people, among the heathen, that they may be brought into communion with Israel and the God of Israel. When the apostles preached the gospel to all nations, beginning at Jerusalem, then this scripture was fulfilled, that his doings should be declared among the people and that what he has done should be known in all the earth. 3. By a holy exultation and transport of joy: "Cry out and shout; welcome the gospel to yourselves and publish it to others with huzzas and loud acclamations, as those that shout for victory (Exod. xxxii. 18) or for the coronation of a king," Num. xxiii. 21.
