Exodus 20:21

18 And, all the people, were witnessing the voices and the torches, and the sound of the horn, and the mountain smoking,—so then the people were struck with awe and shrank back, and stood afar off.

19 And they said unto Moses, Speak, thou, with us, and we will hear,—but let not God speak with us lest we die.

20 And Moses said unto the people—Do not fear, for to the end he may prove you, hath God come,—and to the end the reverence of him may be upon your faces that ye sin not.

21 So then the people stood afar off, and, Moses, approached unto the thick gloom, where God was.

22 Then said Yahweh unto Moses, Thus, shalt thou say, unto the sons of Israel,—Ye yourselves, have seen that out of the heavens, have I spoken with you.

23 Ye shall not make [aught] beside me,—neither gods of silver, nor gods of gold, shall ye make to yourselves.

24 An altar of earth, shalt thou make to me, then shalt thou offer thereupon thine ascending-sacrifices and thy peace-offerings, thy sheep, and thine oxen. In every place where I may mention my name, will I come in unto thee and will bless thee.
