Sirach 24:27-29

Revised Standard Version

²⁷ It makes instruction shine forth like light,
    like the Gihon at the time of vintage.
²⁸ Just as the first man did not know her perfectly,
    the last one has not fathomed her;
²⁹ for her thought is more abundant than the sea,
    and her counsel deeper than the great abyss.
