Isaiah 6:2-3; 1 John 5:7 [Latin]
2 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.
3 And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory.
7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
