They have sown wheat, but shall reap thorns: they have put themselves to pain, but shall not profit: and they shall be ashamed of your harvest because of the fierce anger of the LORD.
All Commentaries on Jeremiah 12:13 Go To Jeremiah 12
Augustine of Hippo
AD 430
“Pray that you do not enter into temptation”—that you enter not again into “contentions, envying, animosities, dissension, detractions, seditions, whispering.” For we have not planted and watered the Lord’s garden in you only to reap these thorns from you. But if your weakness still stirs up a storm, pray that you may be delivered from temptation. Those among you who trouble you, whoever they may be, will incur judgment unless they amend their lives.
