Augustine of Hippo, on Jer 17:5

“Thus saith the Lord: Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the Lord.”

“People who despise being in need before God, lest they receive true perseverance from him, glory in their own false endurance and seek to "confound the counsel of the poor, because the Lord is his hope." Nor do they regard, seeing they are human and attribute so much to their own, that is, to the human will, that they run into that which is written, "Cursed is everyone who puts his hope in humankind."”
