Hymn 19 version 2 (based on the second half of Psalm 19) from our hymn book, Psalms & Hymns of Reformed Worship.

GOD’S precepts are righteous and just,
Rejoicing the heart and the mind;
And all His commandments are pure,
Enlight’ning the eyes of the blind.

The fear of the Lord is most clean,
For ever unmoved has it stood;
His judgements are perfect and true,
In all things most righteous and good.

Such treasure no gold can supply,
Such sweetness no honey afford;
And they who its warnings obey,
Shall find an abundant reward.

O who can his errors discern?
From hidden faults, Lord, keep me free;
Let pride never reign in my heart,
And clear of great sin I shall be.

I pray that my words and my thoughts
May all with Thy precepts accord,
And ever be pleasing to Thee,
My Rock, my Redeemer, my Lord.
