I think you have that psalm wrong. Its not about Bible, but about Israel.
"Because of the misery of the poor, and because of the sighing of the needy, now will I arise, saith the Lord, I will set [them] in safety; I will speak [to them] thereof openly.
The oracles of the Lord are pure oracles; as silver tried in the fire, proved [in] a furnace of earth, purified seven times.
Thou, O Lord, shalt keep us, and shalt preserve us, from this generation, and for ever."
LXX
