Keluaran 19:11

19:11 and be ready for the third day, for on the third day the Lord will come down on Mount Sinai in the sight of all the people.

Keluaran 34:2

34:2 Be prepared ¹  in the morning, and go up in the morning to Mount Sinai, and station yourself ²  for me there on the top of the mountain.

[34:2]  ¹ tn The form is a Niphal participle that means “be prepared, be ready.” This probably means that Moses was to do in preparation what the congregation had to do back in Exod 19:11-15.

[34:2]  ² sn The same word is used in Exod 33:21. It is as if Moses was to be at his post when Yahweh wanted to communicate to him.
