(13) Sing unto the Lord . . .--It was as though heaviness had endured for a night, and joy had come in the morning. As with so many of the Psalms (Psalm 22:22 is, perhaps, the most striking parallel), what began in a cry De profundis ends in a Hallelujah.

Verse 13. - In the confidence of faith Jeremiah sees himself already delivered. He writes in the style of the psalmists, who constantly pass from the language of prayer to that of fruition.

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.Sing unto the Lord, praise ye the Lord,.... The prophet, from prayer, proceeds to praise; and from expressions of faith and confidence in the Lord, having committed his cause to him, being assured of success, rises up to a holy triumph and joy; and calls upon his soul, and upon others, to join with him in praising, and singing praises to the Lord: this is said, as Kimchi observes, with respect to the saints in Jerusalem; for there were some good people doubtless there at this time, a remnant according to the election of grace; who had a regard for the prophet, and wished well to him, and were ready to join with him in acts of devotion, prayer, or praise;

for he hath delivered the soul of the poor from the hand of evil doers; or, "the life of the poor"; meaning himself, a poor destitute person, few or none to stand by him but the Lord, who had delivered him out of the hand of Pashur and his accomplices; and out of the hand of those that watched for his halting; and out of the hands of all his persecutors: or this may respect not past deliverances, but what was to come; which the prophet had such a believing view of, that he calls upon himself and others to praise God for beforehand.
