The A.V. of ver. 17 presents a curious mistake, which the Revisers have omitted to correct. The words should run, as I have rendered them, "Is not _this_"--thy present ill fortune--"the thing that thy forsaking of Iahvah thy God did for thee--at the time when He was guiding thee in the way?" The Hebrew verb does not admit of the rendering in the perf. tense, for it is an impf., nor is it a 2nd pers. fem. (תעשה _not_ תעשי) but a 3rd. The LXX. has it rightly (οὐχὶ ταῦτα ἐποίησέ σοι τὸ καταλιπεῖν σε ἐμέ;), but leaves out the next clause which specifies the time. The words, however, are probably original; for they insist, as vv. 5 and 31 insist, on the groundlessness of Israel's apostasy. Iahvah had given no cause for it; He was fulfilling His part of the covenant by "guiding them in the way." Guidance or leading is ascribed to Iahvah as the true "Shepherd of Israel" (chap. xxxi. 9; Ps. lxxx. 1). It denotes not only the spiritual guidance which was given through the priests and prophets; but also that external prosperity, those epochs of established power and peace and plenty, which were precisely the times chosen by infatuated Israel for defection from the Divine Giver of her good things. As the prophet Hosea expresses it, ii. 8 _sq._, "She knew not that it was I who gave her the corn and the new wine and the oil; and silver I multiplied unto her, and gold, which they made into the Baal. Therefore will I take back My corn in the time of it, and My new wine in its season, and will snatch away My wool and My flax, which were to cover her nakedness." And (chap. xiii. 6) the same prophet gives this plain account of his people's thankless revolt from their God: "When I fed them, they were sated; sated were they, and their heart was lifted up: therefore they forgot Me." It is the thought so forcibly expressed by the minstrel of the Book of the Law (Deut. xxxii. 15), first published in the early days of Jeremiah: "And Jeshurun waxed fat and kicked; Thou waxedst fat, and gross and fleshy! And he forsook the God that made him, And made light of his protecting Rock." And, lastly, the Chronicler has pointed the same moral of human fickleness and frailty in the case of an individual, Uzziah or Azariah, the powerful king of Judah, whose prosperity seduced him into presumption and profanity (2 Chron. xxvi. 16): "When he grew strong, his heart rose high, until he dealt corruptly, and was unfaithful to Iahvah his God." I need not enlarge on the perils of prosperity; they are known by bitter experience to every Christian man. Not without good reason do we pray to be delivered from evil "In all time of our wealth;" nor was that poet least conversant with human nature who wrote that "Sweet are the uses of adversity."
