Charles H. Spurgeon on Psalms 92:10

But my horn shalt thou exalt like the horn of an unicorn. The believer rejoices that he shall not be suffered to perish, but shall be strengthened and enabled to triumph over his enemies, by the divine aid. The unicorn may have been some gigantic ox or buffalo now unknown, and perhaps extinct —among the ancients it was the favourite symbol of unconquerable power; the psalmist adopts it as his emblem. Faith takes delight in foreseeing the mercy of the Lord, and sings of what he will do as well as of what he has done. I shall be anointed with fresh oil. Strengthening shall be attended with refreshment and honour. As guests were anointed at feasts with perfumed unguents, so shall the saints be cheered and delighted by fresh outpourings of divine grace; and for this reason they shall not pass away like the wicked. Observe the contrast between the happiness of the brutish people and the joy of the righteous: the brutish men grow with a sort of vegetable vigour of their own, but the righteous are dealt with by the Lord himself, and all the good which they receive comes directly from his own right hand, and so is doubly precious in their esteem. The psalmist speaks in the first person, and it should be a matter of prayer with the reader that he may be enabled to do the same.
