Psalm 106 begins the same way Psalm 105 ended, with praise and glorification of the Lord for His great goodness and mercy, saying hallelujah! for the many gifts and powerful works that God has done with His people.
This psalm praises God’s great mercy toward a rebellious and ungrateful people, such as the people of Israel on many occasions. There is a sense of supplication in this phrase, one can say that it is as if the psalmist is desperate to obtain greater gratitude from himself and from the Lord’s people.
Clearly we can see that the psalmist, despite the errors of the people, asks God for mercy for Israel and says hallelujah! praise the mercy of God.
Give thanks to the Lord, for he is good;
his love endures forever.
Psalm 106:1
Chapter 105 also shows exaltation toward God for His wonderful works on His people, because His mercies surround His people and deliver them from every oppressor.
And it is evident that when they were in Egypt they sinned against God, and before the Red Sea, they did not remember the multitude of His mercies, but even so God forgave them and continued to deliver them from their enemies.
So, there is much to thank the Lord for. Hallelujah! He helps us and makes the way for us to move forward. Our God is powerful and His goodness and mercy are great, His love is above all things.
