Psalms 71:22
I will also praise thee with the psaltery, even thy truth, O my God: unto thee will I sing with the harp, O thou Holy One of Israel. I will also praise thee with the psaltery, even thy truth, O my God: unto thee will I sing with the harp, O thou Holy One of Israel.
The psalmist praises God as the Holy One of Israel with the psaltery and with the harp, making His truth the theme of the song. The praise continues in the verses that follow by rejoicing with the lips and the soul because God has redeemed the soul, and by speaking of His righteousness. This singing praise to the Holy One of Israel is joyful and continual.
