1. The causes of this sorrow. (1.) The destruction of their cities: For the foundations of Kir-haraseth shall you mourn. That great and strong city, which had held out against a mighty force (2 Kings iii. 25), should now be levelled with the ground, either burnt or broken down, and its foundations stricken, bruised and broken (so the word signifies); they shall howl when they see their splendid cities turned into ruinous heaps. (2.) The desolation of their country. Moab was famous for its fields and vineyards; but those shall all be laid waste by the invading army, v. 8, 10. See, [1.] What a fruitful pleasant country they had, as the garden of the Lord, Gen. xiii. 10. It was planted with choice and noble vines, with principal plants, which reached even to Jazer, a city in the tribe of Gad. The luxuriant branches of their vines wandered, and wound themselves along the ranges on which they were spread, even through the wilderness of Moab. There were vineyards there. Nay, they were stretched out, and went even to the sea, the Dead Sea: the best grapes grew in their hedge-rows. [2.] How merry and pleasant they had been in it. Many a time they had shouted for their summer fruits, and for their harvest, as the country people sometimes do with us when they have cut down all their corn. They had had joy and gladness in their fields and vineyards, singing and shouting at the treading of their grapes. Nothing is said of their praising God for their abundance, and giving him the glory of it. If they had made it the matter of their thanksgiving, they might still have had it the food and fuel of their lusts; see therefore, [3.] How they should be stripped of all. "The fields shall languish, all the fruits of them being carried away or trodden down; they cannot now enrich their owners as they have done, and therefore they languish. The soldiers, called here the lords of the heathen, shall break down all the plants, though they were principal plants, the choicest that could be got. Now the shouting for the enjoyment of the summer fruits has fallen, and is turned into howling for the loss of them. The joy of harvest has ceased; there is no more singing, no more shouting, for the treading out of wine. They have not what they have had to rejoice in, nor have they a disposition to rejoice; the ruin of their country has marred their mirth." Note, First, God can easily change the note of those that are most addicted to mirth and pleasure, can soon turn their laughter into mourning and their joy into heaviness. Secondly, Joy in God is, upon this account, far better than the joy of harvest, that it is what we cannot be robbed of, Ps. iv. 6, 7. Destroy the vines and the fig-trees, and you make all the mirth of a carnal heart to cease, Hos. ii. 11, 12. But a gracious soul can rejoice in the Lord as the God of its salvation even when the fig-tree does not blossom and there is no fruit in the vine, Hab. iii. 17, 18. In God therefore let us always rejoice with a holy triumph, and in other things let us always rejoice with a holy trembling, rejoice as though we rejoiced not.
