(18) Wilt thou be altogether unto me as a liar . . .?--The words express a bitter sense of failure and disappointment. God had not prospered the mission of His servant as He had promised. The Hebrew, however, is not so startlingly bold as the English, and is satisfied by the rendering, wilt thou be unto me as a winter torrent, i.e., as in Job 6:15, like one which flows only in that season, and is dried up and parched in summer. See the play upon the word achzib (= a lie) in Micah 1:14.
Verse 18. - Why is my pain perpetual? One who could honestly speak of himself in terms such as those of Vers. 16, 17, seemed to have a special claim on the Divine protection. But Jeremiah's hopes have been disappointed. His vexation is perpetual, and his wounded spirit finds no comfort. As a liar; rather, as a deceitful stream. The word "stream" has to be understood as in Micah 1:14. Many of the water courses of Palestine are filled with a rushing torrent in the winter, but dry in summer. Hence the pathetic complaint of Job (Job 6:15). The opposite phrase to that used by Jeremiah is "a perennial stream" (Amos 5:24). The force of the passage is increased if we read it in the light of Dr. Gratz's hypothesis.
15:15-21 It is matter of comfort that we have a God, to whose knowledge of all things we may appeal. Jeremiah pleads with God for mercy and relief against his enemies, persecutors, and slanderers. It will be a comfort to God's ministers, when men despise them, if they have the testimony of their own consciences. But he complains, that he found little pleasure in his work. Some good people lose much of the pleasantness of religion by the fretfulness and uneasiness of their natural temper, which they indulge. The Lord called the prophet to cease from his distrust, and to return to his work. If he attended thereto, he might be assured the Lord would deliver him from his enemies. Those who are with God, and faithful to him, he will deliver from trouble or carry through it. Many things appear frightful, which do not at all hurt a real believer in Christ.
Why is my pain perpetual,.... The pain of his mind; his uneasiness for the good of his people, which was likely to last, having no hope of a change for the better: or it may design the pain which they gave him by their reproaches and persecutions of him, which seemed as if they would have no end:
and my wound incurable, which refuseth to be healed? the same thing is meant as before. The allusion is to an old ulcer, or obstinate wound, which no medicine can affect, is desperate and deadly; and such the prophet reckoned his case to be, or however deprecates it, and expostulates with God why it should be so:
wilt thou be altogether unto me as a liar, and as waters that fail? such God cannot be, nor did the prophet think he was; he knew that he was God that could not lie, and that he was faithful to his promises, and would not disappoint the faith, hope, and expectations of his people; but he feared he would be thought to be so by others, by his enemies, who would triumph over him, and say, where is thy God? did he not promise to make thee a defenced city, an iron pillar, and brasen walls? is he as good as his word? is he not like a dry brook, whose waters fail? are not thy hope and expectation in vain, who hast been trusting to him, and depending on him? and it is as if the prophet should say, Lord, let them have no occasion to speak after this manner; nor suffer my faith in thy promises to fail; show thyself to be as thou art, a covenant keeping God, and whose faithfulness never fails: to which an answer is returned in the following verses.
