Here is, I. The prophet prepared to receive the discovery that was to be made to him: The angel that talked with him came and waked him, v. 1. It seems, though he was in conference with an angel, and about matters of great and public concern, yet he grew dull and fell asleep, as it should seem, while the angel was yet talking with him. Thus the disciples, when they saw Christ transfigured, were heavy with sleep, Luke ix. 32. The prophet's spirit, no doubt, was willing to attend to that which was to be seen and heard, but the flesh was weak; his body could not keep pace with his soul in divine contemplations; the strangeness of the visions perhaps stupefied him, and so he was overcome with sleep, or perhaps the sweetness of the visions composed him and even sung him asleep. Daniel was in a deep sleep when he heard the voice of the angel's words, Dan. x. 9. We shall never be fit for converse with spirits till we have got clear of these bodies of flesh. It should seem, the angel let him lose himself a little, that he might be fresh to receive new discoveries, but then waked him, to his surprise, as a man that is wakened out of his sleep. Note, We need the Spirit of God, not only to make known to us divine things, but to make us take notice of them. He wakens morning by morning, he wakens my ear, Isa. l. 4. We should beg of God that, whenever he speaks to us, he would awaken us, and we should then stir up ourselves.
