Psalms 33:4

2 Praise the LORD with harp: sing unto him with the psaltery and an instrument of ten strings.

3 Sing unto him a new song; play skilfully with a loud noise.

For the word of the LORD is right; and all his works are done in truth.

5 He loveth righteousness and judgment: the earth is full of the goodness of the LORD.

6 By the word of the LORD were the heavens made; and all the host of them by the breath of his mouth.

Do read the surrounding verses too, because the context often says more than a single verse.
