Blest are the undefiled in heart,
whose ways are right and clean;
who never from your law depart,
but flee from every sin.
Blest are the ones that keep your word,
and serve you with their hands;
with their whole heart they seek you, Lord,
obeying your commands.
Great is their peace who love your law;
how firm their souls abide!
Nor can a bold temptation draw
their steady feet aside.
Then shall my heart have inward joy!
I’ll keep my steps from shame;
your statutes help me to obey,
and glorify your name.
