O Rex Gentium

O Rex Gentium, et desideratus earum,
lapisque angularis, qui facis utraque unum:
veni, et salva hominem,
quem de limo formasti.

O King of the nations, and their desire,
the cornerstone making both one:
Come and save the human race,
which you fashioned from clay.

This one is text from Isaiah that you’ll recognize:

"For a child has been born for us, a son given us; authority rests
upon his shoulders; and he is named Wonderful Counsellor, Mighty
God, Everlasting Father, Prince of Peace." Isaiah 9:6

And some from Isaiah that you may not:

"He shall judge between the nations, and shall arbitrate for many
peoples; they shall beat their swords into ploughshares, and their
spears into pruning-hooks; nation shall not lift up sword against
nation, neither shall they learn war anymore." Isaiah 2:4
