But the work was but partly done. Difficulties and hardships were not abolished from the world, as Israel had half expected in the first flush of joy. We all are apt to think so, when some long wished and faintly hoped-for good is ours at last. But not such is the Divine purpose for any life here. He gives moments of untroubled joy, when no cloud stains the blue and all the winds are still, in order to prepare us for toil amid tempests and gloomy skies. So the second half of the psalm breathes petitions for the completion of the Restoration, and animates the returned exiles with assurances that, whatever may be their toils, and however rough the weather in which they have to sow the seed, and however heavy the hearts with which they do it, "the slow result of winter showers" is sure. Lessons of persevering toil, of contented doing of preparatory work, of confidence that no such labour can fail to be profitable to the doer and to the world, have been drawn for centuries from the sweet words of this psalm. Who can tell how many hearts they have braced, how much patient toil they have inspired? The psalmist was sowing seed, the fruit of which he little dreamed of, when he wrote them, and his sheaves will be an exceeding weight indeed. The metaphor in ver. 4 brings before the imagination the dried torrent-beds in the arid Negeb, or Southland, which runs out into the Arabian desert. Dreary and desolate as these dried wadies lie bleaching in the sunshine, so disconsolate and lonely had the land been without inhabitants. The psalmist would fain see, not the thin trickle of a streamlet, to which the returned captives might be compared, but a full, great rush of rejoicing fellow-countrymen coming back, like the torrents that fill the silent watercourses with flashing life.
