I will praise thee with uprightness of heart, when I shall have learned thy righteous judgments.
I will praise thee with uprightness of heart (i:e., sincerity; as opposed to formal lip service), when I shall have learned thy righteous judgments - when I shall have been taught by thee the laws of thy righteousness. To praise God aright, we must learn by the Divine Spirit's teaching the holiness of God, reflected in His word and laws (Psalms 119:12; Psalms 119:26; John 6:45).
