My heart is steadfast, O God,
my heart is steadfast;
I will sing and make music.
Awake, my soul!
Awake, harp and lyre!
I will awaken the dawn.
I will praise you, O Lord, among the nations;
I will sing of you among the peoples.
For great is your love, reaching to the heavens;
your faithfulness reaches to the skies.
Be exalted, O God, above the heavens;
let your glory be over all the earth.
— Psalm 57:7-11
