4 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.
5 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.
