Praise the Lord with the harp;

make music to him on the ten-stringed lyre.

3Sing to him a new song;

play skillfully, and shout for joy.

4For the word of the Lord is right and true;

he is faithful in all he does.

5The Lord loves righteousness and justice;

the earth is full of his unfailing love. Psalm 33:2-5
