This is the first of the seven 'O' Antiphons (this is the wikipedia link)
It is usually sung on 17th December, at vespers, the others following every evening until the day before Christmas Eve.
O Wisdom,
coming forth from the mouth of the Most High,
reaching from one end to the other,
mightily and sweetly ordering all things:
Come and teach us the way of prudence.

O Sapientia: “O Wisdom, O holy Word of God, you govern all creation with your strong yet tender care. Come and show your people the way to salvation.”
Isaiah had prophesied,
“The spirit of the Lord shall rest upon him: a spirit of wisdom and of understanding, a spirit of counsel and of strength, a spirit of knowledge and fear of the Lord, and his delight shall be the fear of the Lord.” (11:2-3)
“Wonderful is His counsel and great is His wisdom.” (28:29).
