Ecclesiastes 1:18

Septuagint · public domain
Thomson 1808
I have found by experience that this also is indeed vexation of spirit. Because by much wisdom there is much knowledge: and he who addeth to his knowledge will add to his sorrow.
Brenton 1851
For in the abundance of wisdom is abundance of knowledge; and he that increases knowledge will increase sorrow.
Greek · Brenton
Ὅτι ἐν πλήθει σοφίας πλῆθος γνώσεως, καὶ ὁ προστιθεὶς γνῶσιν, προσθήσει ἄλγημα.
