'Gratitude' in the Bible

“Because you did not serve the Lord your God with a heart full of joy and gladness for the abundance of all things [with which He blessed you],

On the eighth (fifteenth) day he sent the people away and they blessed the king. Then they went to their tents joyful and in good spirits because of all the goodness which the Lord had shown to David His servant and Israel His people.

The Lord strengthens and protects me; I trust in him with all my heart. I am rescued and my heart is full of joy; I will sing to him in gratitude.
