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.”

“We have recognized ourselves, seen ourselves and taken a thorough look at ourselves. Let us groan and sigh in ourselves, pour out prayers, that we enter not into temptations. We must not rely on our own powers to overcome all these things. Blessed, after all, is the one whose helper is the God of Jacob, his hope in the Lord his God, not in himself, because he is a mere mortal. But cursed is everyone who places his hope in humankind.”
