Original Trinity Hymnal, #450
From Psalm 19:7-11 and Psalm 119:97

Most perfect is the law of God,
Restoring those that stray;
His testimony is most sure,
Proclaiming wisdom's way.

O how love I thy law! O how love I thy law!
It is my meditation all the day.
O how love I thy law! O how love I thy law!
It is my meditation all the day.

The precepts of the Lord are right;
With joy they fill the heart;
The Lord's commandments all are pure,
And clearest light impart.

The fear of God is undefiled
And ever shall endure;
The statutes of the Lord are truth
And righteousness most pure.

They warn from ways of wickedness
Displeasing to the Lord,
And in the keeping of his Word
There is a great reward.
