Daniel 8:15

Here we have, I. Daniel's earnest desire to have this vision explained to him (Dan 8:15): I sought the meaning. Note, Those that rightly know the things of God cannot but desire to know more and more of them, and to be led further into the mystery of them; and those that would find the meaning of what they have seen or heard from God must seek it, and seek it diligently. Seek and you shall find. Daniel considered the thing, compared it with the former discoveries, to try if he could understand it; but especially he sought by prayer (as he had done Dan 2:18), and he did not seek in vain. II. Orders given to the angel Gabriel to inform him concerning this vision. One in the appearance of a man (who, some think, was Christ himself, for who besides could command angels?) orders Gabriel to make Daniel understand this vision. Sometimes God is pleased to make use of the ministration of angels, not only to protect his children, but to instruct them, to serve the kind intentions, not only of his providence, but of his grace. III. The consternation that Daniel was in upon the approach of his instructor (Dan 8:17): When he came near I was afraid. Though Daniel was a man of great prudence and courage, and had been conversant with the visions of the Almighty, yet the approach of an extraordinary messenger from heaven put him into this fright.
