Yet heard I the voice of his words - What the angel said when he appeared to him Daniel has not recorded. He says Daniel 10:6 that the voice of his words was “like the voice of a multitude.” It is probable that those who were with him had heard that voice, and hearing it, and being struck with the remarkable character of the vision, they had suddenly fled in alarm. Daniel heard more distinctly what he said, though it does not yet appear that he had heard anything more than the sound of his voice.
And when I heard the voice of his words, then was I in a deep sleep on my face - Compare the notes at Daniel 8:18. Lengerke renders this, “I sank into a deep sleep,” etc. This is undoubtedly the meaning, that when he heard this voice he was overcome, and sank prostrate and senseless upon the earth. The sense of the Hebrew may be thus expressed: “I became (הייתי hâyı̂ytı̂y) oppressed with sleep,” etc.
