In personifying the wall of Zion, however, the Hebrew poet does not indulge in reflections such as these, which are more in harmony with the mild melancholy of Gray's _Elegy_ than with the sadder mood of the mourning patriot. He names the wall to give unity and concreteness to his appeal, and to clothe it in an atmosphere of poetic fancy. But his sober thought in the background is directed towards the citizens whom that historic wall once enclosed. Herein is his justification for carrying his personification so far. This is more than a wild apostrophe, the outburst of an excited poet's fancy. The imaginative conceit wings the arrow of a serious purpose. Let us look at the appeal in detail. First the elegist encourages a free outflow of grief, that tears should run like a river, literally, like a torrent--the allusion being to one of those steep watercourses which, though dry in summer, become rushing floods in the rainy season. This introduction shews that the call to prayer is not intended in any sense as a rebuke for the natural expression of grief, nor as a denial of its existence. The sufferers cannot say that the poet does not sympathise with them. It might seem needless to give this assurance. But anybody who has attempted to offer exhortation to a person in trouble must have discovered how delicate his task is. Let him approach the subject as carefully as he may, it is almost certain that he will chafe the quivering nerves he desires to soothe, so sensitive is the soul in pain to any interference from without. Under these circumstances, the one method by which it is at all possible to smooth the way of approach is an expression of genuine sympathy. There may be a deeper reason for this encouragement of the expression of grief as a preliminary to a call to prayer. The helplessness which it so eloquently proclaims is just the condition in which the soul is most ready to cast itself on the mercy of God. Calm fortitude must always be better than an undisciplined abandonment to grief. But before this has been attained there may come an apathy of despair, under the influence of which the feelings are simply benumbed. That apathy is the very opposite to drying up the fountain of grief as it may be dried in the sunshine of love; it is freezing it. The first step towards deliverance will be to melt the glacier. The soul must feel before it can pray. Therefore the tears are encouraged to run like torrents, and the sufferer to give himself no respite, nor let the apple of his eye cease from weeping.
