Blest are the undefiled in heart,
Whose ways are right and clean;
Who never from thy law depart,
But fly from every sin.

Blest are the men that keep thy word,
And practise thy commands;
With their whole heart they seek the Lord,
And serve thee with their hands.

Great is their peace who love thy law;
How firm their souls abide!
Nor can a bold temptation draw
Their steady feet aside.

Then shall my heart have inward joy,
And keep my face from shame,
When all thy statutes I obey,
And honor all thy name.

But haughty sinners God will hate,
The proud shall die accursed;
The sons of falsehood and deceit
Are trodden to the dust.

Vile as the dross the wicked are;
And those that leave thy ways
Shall see salvation from afar,
But never taste thy grace.

The Psalms and Hymns of Isaac Watts
