In this chapter we have an account that Moses was ordered to come up to the Lord alone, Ex 24:1,2, but that before he did go up, he related to the people all the above laws delivered to him, which they promised obedience to, and so a covenant was made between God and the people by sacrifice, and by the sprinkling of blood, Ex 24:3-8, upon which he and Aaron, and his two sons and seventy elders of Israel, went up part of the mountain, and had a vision of God, Ex 24:9-11, when Moses with Joshua was called, and went up higher, until at length he entered into the cloud where the Lord was, and continued forty days and forty nights, Ex 24:12-18.
