신명기 5:19의 주석

ולא יסף — We render this in the Targum by ולא פסק “and He did not cease”, — [Because it is characteristic of human beings that they are unable to utter all their words in one breath (but must make pauses) and it is characteristic of the Holy One, blessed be He, that this is not so, therefore He did not pause, and since He did not pause, He did not have to resume], — for His voice is strong and goes on continuously (Sanhedrin 17a). Another explanation of ולא יסף: He did not again ever reveal himself with such publicity.

OUT OF THE MIDST OF THE FIRE, OF THE CLOUD, AND OF THE THICK DARKNESS. “The cloud and the darkness” explain the expression out of the midst of the fire, for Clouds and darkness are round about Him.¹⁷⁶Psalms 97:2.

את הדברים האלה דבר השם, "These are the words which G'd spoke, etc." Moses omitted to say "all these words," seeing that some of the words which appeared here were not G'd's words but his own, such as when he said: "as G'd commanded you, etc."
