How does the Second Vatican Council document Dei Verbum (see chapter 3 from assigned reading) emphasize the importance of recognizing both the divine and human authorship of sacred Scripture?

11. Those divinely revealed realities which are contained and presented in Sacred Scripture have been committed to writing under the inspiration of the Holy Spirit. For holy mother Church, relying on the belief of the Apostles (see John 20:31; 2 Tim. 3:16; 2 Peter 1:19-20, 3:15-16), holds that the books of both the Old and New Testaments in their entirety, with all their parts, are sacred and canonical because written under the inspiration of the Holy Spirit, they have God as their author and have been handed on as such to the Church herself.(1) In composing the sacred books, God chose men and while employed by Him (2) they made use of their powers and abilities, so that with Him acting in them and through them, (3) they, as true authors, consigned to writing everything and only those things which He wanted. (4)

Therefore, since everything asserted by the inspired authors or sacred writers must be held to be asserted by the Holy Spirit, it follows that the books of Scripture must be acknowledged as teaching solidly, faithfully and without error that truth which God wanted put into sacred writings (5) for the sake of salvation. Therefore "all Scripture is divinely inspired and has its use for teaching the truth and refuting error, for reformation of manners and discipline in right living, so that the man who belongs to God may be efficient and equipped for good work of every kind" (2 Tim. 3:16-17, Greek text).

12. However, since God speaks in Sacred Scripture through men in human fashion, (6) the interpreter of Sacred Scripture, in order to see clearly what God wanted to communicate to us, should carefully investigate what meaning the sacred writers really intended, and what God wanted to manifest by means of their words.

To search out the intention of the sacred writers, attention should be given, among other things, to "literary forms." For truth is set forth and expressed differently in texts which are variously historical, prophetic, poetic, or of other forms of discourse. The interpreter must investigate what meaning the sacred writer intended to express and actually expressed in particular circumstances by using contemporary literary forms in accordance with the situation of his own time and culture. (7) For the correct understanding of what the sacred author wanted to assert, due attention must be paid to the customary and characteristic styles of feeling, speaking and narrating which prevailed at the time of the sacred writer, and to the patterns men normally employed at that period in their everyday dealings with one another. (8)

But, since Holy Scripture must be read and interpreted in the sacred spirit in which it was written, (9) no less serious attention must be given to the content and unity of the whole of Scripture if the meaning of the sacred texts is to be correctly worked out. The living tradition of the whole Church must be taken into account along with the harmony which exists between elements of the faith. It is the task of exegetes to work according to these rules toward a better understanding and explanation of the meaning of Sacred Scripture, so that through preparatory study the judgment of the Church may mature. For all of what has been said about the way of interpreting Scripture is subject finally to the judgment of the Church, which carries out the divine commission and ministry of guarding and interpreting the word of God.

13. In Sacred Scripture, therefore, while the truth and holiness of God always remains intact, the marvelous "condescension" of eternal wisdom is clearly shown, "that we may learn the gentle kindness of God, which words cannot express, and how far He has gone in adapting His language with thoughtful concern for our weak human nature." (11) For the words of God, expressed in human language, have been made like human discourse, just as the word of the eternal Father, when He took to Himself the flesh of human weakness, was in every way made like men.
