Psalm 40 for half marathon

I waited patiently for the Lord;
    he inclined to me and heard my cry.
He drew me up from the pit of destruction,
    out of the miry bog,
and set my feet upon a rock,
    making my steps secure.
He put a new song in my mouth,
    a song of praise to our God.
Many will see and fear,
    and put their trust in the Lord.
–Psalm 40:1-3
