I believe that the key to understanding what the Bible means is in the Baha'i Writings.
“Know assuredly that just as thou firmly believest that the Word of God, exalted be His glory, endureth for ever, thou must, likewise, believe with undoubting faith that its meaning can never be exhausted. They who are its appointed interpreters, they whose hearts are the repositories of its secrets, are, however, the only ones who can comprehend its manifold wisdom. Whoso, while reading the Sacred Scriptures, is tempted to choose therefrom whatever may suit him with which to challenge the authority of the Representative of God among men, is, indeed, as one dead, though to outward seeming he may walk and converse with his neighbors, and share with them their food and their drink.”
Baha’u’llah was referring to the Bible as the Word of God. What Baha’u’llah was saying in that passage is that the biblical scriptures can have many different, but the Representative of God and His appointed interpreters are the only ones who have the authority to interpret the scriptures, so they are the final authorities on the meaning so whatever meaning they assign should not be questioned.
I believe that the Representative of God is the Messenger of God, Baha'u'llah, also referred to as a Manifestation of God.
Abdu'l-Baha and Shoghi Effendi were Baha'u'llah's appointed interpreters.
