Restored Israel calls upon the nations to praise the Lord.
(vs. 1) Israel established in Jerusalem, as described in the end of the previous psalm now calls upon all nations and peoples to praise the Lord.
(vs. 2) They can thus call upon others to praise the Lord, because of what they have experienced themselves― “His merciful kindness is great toward us.” They at last own they have come into blessing on the ground of mercy (cf. Rom. 11:31-3231Even so have these also now not believed, that through your mercy they also may obtain mercy. 32For God hath concluded them all in unbelief, that he might have mercy upon all. (Romans 11:31‑32)). Nevertheless, they recognize it is not mercy at the expense of truth. God has shown mercy but maintained truth. The truth has not been set aside; it endures forever. “Praise ye the LORD.”
