Psalm 106:1-3 (NKJV)
Praise the Lord!
Oh, give thanks to the Lord,
   for He is good!
For His mercy endures forever.
Who can utter the mighty acts of the Lord?
   Who can declare all His praise?
Blessed are those who keep justice,
   And he who does righteousness at all times!

Psalm 105:3-5 (ESV)
Glory in his holy name;
    let the hearts of those who seek the Lord rejoice!
Seek the Lord and his strength;
    seek his presence continually!
Remember the wondrous works that he has done,
    his miracles, and the judgments he uttered
