Begin, my tongue, some heavenly theme,
And speak some boundless thing;
The mighty works or mightier name
Of our eternal King.

2 Tell of his wondrous faithfulness,
And sound his power abroad;
Sing the sweet promise of his grace,
And the performing God.

3 His very word of grace is strong,
As that which built the skies;
The voice that rolls the stars along,
Speaks all the promises.

4 Oh, might I hear thy heavenly tongue
But whisper, "Thou art mine!"
Those gentle words should raise my song
To notes almost divine.

Isaac Watts.
