Jeremiah 20:11 - Wesley's Explanatory Notes

But — The prophet recovering himself out of his fit of passion, encourageth himself in his God, whom he calls the mighty and terrible one, so declaring his faith in the power of God, as one able to save him, and in the promise and good will of God toward him; therefore he saith, The Lord is with me; such was the promise of God to this prophet, when he first undertook the prophetical office, Jeremiah 1:8. Be not afraid of their faces, for I am with thee to deliver thee saith the Lord: from hence be concludes, that though he had many that pursued after his life, yet they should stumble in their ways of violence, and should not prevail. Ashamed — That they should be ashamed of what they had done, or be brought to shame for what they had done; for prosper they should not: or they acted like fools, and did not deal prudently for themselves (so this word is translated, Isaiah 52:13,) yea, they should become a reproach, and their reproach should be a lasting perpetual reproach that should not be forgotten.
