Antiphon: Lauds: The Circumcision of the Lord: Joshua 6:36ff.

Quando natus es ineffabiliter ex Virgine, tunc impletae sunt scripturae :sicut pluvia in vellus descendisti,ut salvum faceres genus humanum te laudamus, Deus noster.

When you were born ineffably of a Virgin, then were the Scriptures fulfilled: you came down like the rain into a fleece of wool, to bring salvation unto all mankind: we praise you, our God.
