Charles H. Spurgeon on Psalms 94:19

Thoughts considered simply in themselves do not contain any matter of grief or evil; they are the proper and natural issue and emanations of the soul which come from it with a great deal of easiness, and with a great deal of delight; but it is the exorbitance and irregularity of them which is here intended, when they do not proceed evenly and fairly, as they ought to do, but with some kind of interruption;and so the word which is here used in the text seems to import; the Hebrew sagnaphim carrying an affinity with segnaphim, which is derived from a root which signifies properly a bough. Now we know that in a bough there are two things especially considerable, as pertinent to our present purpose. First, there's the perplexity of it. And, secondly, there's the agitation. Boughs usually catch, and entangle one another, and boughs they are easily shaken, and moved up and down by the wind. If there be never so little air or breath stirring abroad, the boughs presently discover it, and are made sensible of it. So that this expression does serve very well to imitate and set forth unto us the perplexity and inconstancy of thoughts, which David was now troubled withal, and whereof he now complains, as grievous and offensive to him. They were not thoughts in any consideration, but thoughts of distraction, such thoughts as did bring some grief and trouble with them. This the Septuagint translators were so fully apprehensive of, that they quite leave out thoughts, and render it only by griefs, kata to pkhyov twn odunwn mou: according to the multitude of my sorrows. But it is more full and agreeable to the word to put them both together —my grievous and sorrowful thoughts —such thoughts as in regard of the carriage and ordering of them, do bring grief and sorrow with them. And here we may by the way observe thus much, that God need not go far to punish and afflict men when he pleases; he can do it even with their own thoughts, no more but so. He can gather a rod of these boughs, and make a scourge of these twistings, wherewith to lash them, and that to purpose. If he does but raise a tempest in the mind, and cause these thoughts to bluster and bustle one with another, there will be trouble and affliction enough, though there were nothing else. It is no matter whether there be any ground or occasion for it in the things themselves; it is enough that there be so but in the conceit and apprehension. God can so use a fancy, a mere toy and imagination itself, and so set it on upon the soul, that there shall be no quiet nor rest for it. Thomas Horton.
