O Sapientia, quae ex ore Altissimi prodidisti, attingens a fine usque ad finem, fortiter suaviter disponensque omnia: veni ad docendum nos viam prudentiae.
O Wisdom, who came from the mouth of the Most High, reaching from end to end and ordering all things mightily and sweetly, Come, and teach us the way of prudence.
And the spirit of the Lord shall rest upon him: the spirit of wisdom, and of understanding, the spirit of counsel, and of fortitude, the spirit of knowledge, and of godliness. And he shall be filled with the spirit of the fear of the Lord, He shall not judge according to the sight of the eyes, nor reprove according to the hearing of the ears.
This also is come forth from the Lord God of hosts, to make his counsel wonderful, and magnify justice.
