Domine deus uirtutum quis simi-
lis tibi : potens es domine et ueritas
tua in circuitu tuo .

In a modern biblical layout, this would read:

Domine deus uirtutum quis similis tibi: potens es domine et ueritas tua in circuitu tuo.

Translation from the Douai version of the Bible: [Psalm 88, verse 9]

O Lord God of hosts, who is like unto Thee? Thou art mighty, O Lord,
and Thy truth is round about Thee.
