Shemot 24:1-2

Orthodox Jewish Bible

24 And He said unto Moshe, Come up unto Hashem, thou, and Aharon, Nadav, and Avihu, and shive’im (seventy) of the Ziknei Yisroel; and worship ye afar off.

² And Moshe alone shall come near Hashem; but they shall not come near; neither shall HaAm go up with him.
