2:9 Because of their unparalleled idolatry, the Lord promised to contest His people. Even their grandchildren would experience His discipline because of the sins of their forefathers.
". . . Scripture often stresses the solidarity of one generation with another, endorsing our sense of pride or shame over our collective past."75
2:10-11 The Lord challenged His people to look to other nations to see if any of them had done what they had done. None of their neighbor nations had ever forsaken gods whom they thought had blessed them in the past. This was true of them all, from Kittim (Cyprus) to Israel's northwest to Kedar (in the Arabian Desert) to the southeast (cf. Gen. 10:4; 25:13). Yet the Israelites had forsaken the only true God who had made them a glorious people for gods that did not give them anything.
2:12 Yahweh called the heavens as witnesses to Israel's folly (cf. Deut. 32:1; Isa. 1:2; Mic. 6:1; et al.). They could only be appalled and shudder at such foolishness and feel desolate over such apostasy.
2:13 The Israelites had committed two evils, one a sin of omission and the other a sin of commission. They had forsaken Yahweh who, like a fountain, had provided for their deepest needs (cf. Ps. 36:9; John 4:10-14; Rev. 21:6). And they had pursued idols who, like broken cisterns, could not even hold water much less provide it. The most reliable source of water in Israel was a natural spring, and the least reliable was a cistern.
"The best cisterns, even those in solid rock, are strangely liable to crack, and are a most unreliable source of supply of that absolutely indispensable article, water; and if, by constant care, they are made to hold, yet the water, collected from clay roofs or from marly soil, has the color of weak soapsuds, the taste of the earth or the stable, is full of worms, and in the hour of greatest need it utterly fails. Who but a fool positive, or one gone mad in love of filth, would exchange the sweet, wholesome stream of a living fountain for such an uncertain compound of nastiness and vermin!"76
