Kohelet 1:16-18

Orthodox Jewish Bible

¹⁶ I communed with mine own lev, saying, Hinei, I am come to greatness, even greater chochmah than all they that have been before me over Yerushalayim; yea, my lev had great experience of chochmah and da’as.

¹⁷ And I applied my lev to have da’as of chochmah, and to have da’as of holelot (madness) and sichlut (folly); I perceived that this also is striving after ruach (wind).

¹⁸ For in much chochmah (wisdom) is much ka’as (grief, vexation); and he that increaseth da’as increaseth mach’ov (sorrow).
