Thus says the LORD;
Cursed be the man that trusts in man, and makes flesh his arm, and whose heart departs from the LORD.
All Commentaries on Jeremiah 17:5 Go To Jeremiah 17
Augustine of Hippo
AD 430
Take care not to let trust in your own strength steal on you, for you are human, and “cursed is everyone who puts his hope in humankind.” But put your trust fully and with your whole heart in God, and he will be your strength. Trust him lovingly and gratefully and say to him humbly and faithfully, “Trust in the Lord with your whole heart; he will be your strength.”
