I saw the Lord, sitting upon a throne, high and lifted up,
and his train filled the temple.
Above it stood the seraphims: each one had six wings;
with twain he covered his face,
and with twain he covered his feet,
and with twain he did fly.
And one cried unto another,
Holy, Holy, Holy is the Lord of Hosts:
the whole earth is full of his glory.
And the posts of the door moved at the voice of him that cried,
and the house was filled with smoke.
O Trinity! O Unity!
Be present as we worship Thee,
And with the songs that angels sing
Unite the hymns of praise we bring.
Amen.
