A mighty terrible one - Rather, "a terrible warrior." The mighty One Isaiah 9:6 who is on his side is a terror to them. This change of feeling was the effect of faith, enabling him to be content with calmly doing his duty, and leaving the result to God.

For ... - Rather, "because they have not acted wisely (Jeremiah 10:21 note), with an everlasting disgrace that shall never be forgotten."

But the Lord is with me as a mighty terrible one - Thus was he, by his strong confidence in the strong God, delivered from all his fears, and enabled to go on comfortably with his work.

But the Lord is with me as a mighty terrible one,.... The Targum is,

"the Word of the Lord is for my help.''

"Mighty" to support, uphold, defend, and deliver him; and "terrible" to his enemies. The prophet looks back to the promise the Lord had made him, of his gracious and powerful presence, Jeremiah 1:18; which he now takes comfort from; and it would have been well if he had kept this always in view, and had continued in the same actings of faith and temper of mind: but this lasted not long, as some following verses show;

therefore my persecutors shall stumble, and shall not prevail; though they should very hotly and furiously pursue him, yet they should stumble and fall by the way, and not be able to overtake him, and execute their designs upon him; the Lord, who was with him, and on his side, would throw some things in their way, at which they should stumble, and which should hinder them from proceeding;

they shall be greatly ashamed, for they shall not prosper; when they see their schemes are disappointed, and they do not succeed, they shall be filled with shame and confusion: or, "because they do not deal prudently" (g), as the word is rendered, Isaiah 52:13; they do not act a wise, but a foolish part, and therefore shame will be the consequence of it;

their everlasting confusion shall never be forgotten; neither by themselves nor others; the memory of it will always continue, to their everlasting grief and reproach. A very learned man connects these words with the former, thus, "they shall be greatly ashamed, for they shall not prosper, with an everlasting shame never to be forgotten" (h), very rightly; so another learned interpreter (i).

(g) "quia non prudenter egerunt", Montanus, Piscator; "prudenter agunt", Calvin. (h) "Erubescent valde, quia non prosperabuntur, ignominia aeterna non obliviscenda", De Dieu. (i) "Pudefient, quod non profecerint, ignominia perpetuitatis (quae) non tradetur oblivioni", Schmidt.

{g} But the LORD is with me as a mighty terrible one: therefore my persecutors shall stumble, and they shall not prevail: they shall be greatly ashamed; for they shall not prosper: their everlasting confusion shall never be forgotten.

(g) Here he shows how his faith strove against temptation and sought the Lord for strength.

20:11 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, chap.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, Isa 52:13,) yea, they should become a reproach, and their reproach should be a lasting perpetual reproach that should not be forgotten.

11. not prevail-as they hoped to do (Jer 20:10; Jer 15:20).

prosper-in their plot.

20:7-13 The prophet complains of the insult and injury he experienced. But ver. 7 may be read, Thou hast persuaded me, and I was persuaded. Thou wast stronger than I; and didst overpower me by the influence of thy Spirit upon me. So long as we see ourselves in the way of God, and of duty, it is weakness and folly, when we meet with difficulties and discouragements, to wish we had never set out in it. The prophet found the grace of God mighty in him to keep him to his business, notwithstanding the temptation he was in to throw it up. Whatever injuries are done to us, we must leave them to that God to whom vengeance belongs, and who has said, I will repay. So full was he of the comfort of God's presence, the Divine protection he was under, and the Divine promise he had to depend upon, that he stirred up himself and others to give God the glory. Let the people of God open their cause before Him, and he will enable them to see deliverance.
