Sirach 24:3
Ben Sira, Ecclesiasticus1 Wisdom praises herself, and tells of her glory in the midst of her people. 2 In the assembly of the Most High she opens her mouth, and in the presence of his hosts she tells of her glory: 3 "I came forth from the mouth of the Most High, and covered the earth like a mist. 4 I dwelt in the highest heavens, and my throne was in a pillar of cloud. 5 Alone I compassed the vault of heaven and traversed the depths of the abyss.
Ambrose On the Christian Faith 4.8
We say, therefore, that it is the function and exercise of His Authority that He has made us sons of God, whereas the oracles of God discover that His generation is in relation to personal attribute, for the Wisdom of God says: I came forth out of the mouth of the Most High, that is to say not of compulsion, but free, not under bond of authority, but born in a hidden birth, according to personal powers of Supreme Sovereignty and rightfulness of authority. Again, concerning the same Wisdom, Which is the Lord Jesus, the Father says in another place: Out of the womb I begot You, before the morning star.
Notes and References
"... The Book of Ecclesiasticus [Sirach] has been honored still more highly among the Christians, being cited in the Epistle of James (Edersheim, in Wace, 'Apocrypha,' p. 21), the Didache (4:5), and the Epistle of Barnabas (19:9), while Clement of Alexandria and Origen quote from it repeatedly, as from a γραφή, or holy book. In the Western Church, Cyprian frequently appeals to it in his 'Testimonia,' as does Ambrose in the greater number of his writings. In like manner the Catalogue of Cheltenham, Damasus I., the Councils of Hippo (393) and Carthage (397), Pope Innocent I., the second Council of Carthage (419), and Augustine all regard it as a canonical book. This is contrary, however, to the opinions of the Council of Laodicea, of Jerome, and of Rufinus of Aquileia, which authorities rank it among the ecclesiastical books. It was finally declared canonical by the Council of Trent; and the favor with which the Church has always regarded it has preserved it in its entirety. ..."
