God’s wondrous ways to Israel are to be proclaimed to all nations, that these nations too may acknowledge God and enjoy His protection. God’s mercy was not meant for Israel alone (see Ps. 105:1). This sentiment occurs throughout the psalms. If Israel had learned this lesson, the rigid exclusiveness practiced by the Pharisees would never have existed.
Sing praises.
In view of God’s holy character and His kindness to men, the psalmist calls on others to praise God with him.
