The labour of compiling the notes of this volume may be judged of from the fact that upon my writing to one of the most scholarly men of this age for a little assistance in my researches upon that well-known Psalm, the 103rd I received a note commencing, "I have hunted through my books, and have been surprised to find that, with the exception of what is universally known, there is so little about Psalm 103." This most generous-hearted brother had the warmest zeal and love to stimulate his investigations, yet this was the result, and had I repeated the experiment upon other Biblical students, and changed the Psalm, I should in very few instances have received any other reply. Hence, gentle reader, your patience has been exercised in waiting for Vol. IV. of the Treasury, and my toil has been correspondingly increased. Here, however, is the volume, as portly as its fellows, and I hope not inferior to any of them; at least, I can honestly say, if it be so, it is not the fault of my endeavours, for I have bated no jot of energy, spared no cost, and withheld no time, though this last has been a very precious commodity with me, and has frequently been snatched from rest which fatigue demanded, and which prudence might have wisely yielded.<br><br>Nor is this the only reason for the time which this volume has occupied, though we judge it to be quite sufficient, but we have desired to complete this work at our best, and not to allow the close of it to exhibit signs of fatigue and decline. We have often sat down to write our comment upon a Psalm, and have risen from the task because we did not feel at home at it. It is of no use compelling the mind, its productions in such a case are like forced fruits, disappointing and devoid of flavour. We like to write after the manner of John Bunyan, who said, "As I pulled, it came," and we prefer that the pulling should be as gentle as possible. So it has happened that we have lingered for months over a Psalm, feeling quite unfit to enter upon it. Especially was this the case over the hundred and ninth Psalm, which we sometimes think we never should have been able to handle at all if it had not been for the Bulgarian massacres, which threw us into such a state of righteous indignation that while we were musing the fire burned, and we melted the sentences, and wished that we could pour them boiling hot upon the monsters. Later tidings make us feel that the other side might well be favoured with similar visitations. Other Psalms have had their difficulties, though none to be compared with CIX. The grand Cosmos of Psalm CIV. was not to be dismissed in a few days; even now, after laying our best efforts at its feet, we feel dissatisfied with the poor result.
