9 Then Moses and Aaron, Nadab, and Abihu, and seventy of the elders of Israel went up, 10 and they saw the God of Israel. Under his feet there was something like a pavement of sapphire stone, like the very heaven for clearness. 11 God did not lay his hand on the chief men of the people of Israel; also they beheld God, and they ate and drank.

12 The Lord said to Moses, "Come up to me on the mountain, and wait there; and I will give you the tablets of stone, with the law and the commandment, which I have written for their instruction." 13 So Moses set out with his assistant Joshua, and Moses went up into the mountain of God. 14 To the elders he had said, "Wait here for us, until we come to you again; for Aaron and Hur are with you; whoever has a dispute may go to them." 15 Then Moses went up on the mountain, and the cloud covered the mountain. 16 The glory of the Lord settled on Mount Sinai, and the cloud covered it for six days; on the seventh day he called to Moses out of the cloud. 17 Now the appearance of the glory of the Lord was like a devouring fire on the top of the mountain in the sight of the people of Israel. 18 Moses entered the cloud, and went up on the mountain. Moses was on the mountain for forty days and forty nights.

Commentary on Exodus 24:9-11

(Read Exodus 24:9-11)

The elders saw the God of Israel; they had some glimpse of his glory, though whatever they saw, it was something of which no image or picture could be made, yet enough to satisfy them that God was with them of a truth. Nothing is described but what was under his feet. The sapphires are the pavement under his feet; let us put all the wealth of this world under our feet, and not in our hearts. Thus the believer sees in the face of Jesus Christ, far clearer discoveries of the glorious justice and holiness of God, than ever he saw under terrifying convictions; and through the Saviour, holds communion with a holy God.

Commentary on Exodus 24:12-18

(Read Exodus 24:12-18)

A cloud covered the mount six days; a token of God's special presence there. Moses was sure that he who called him up would protect him. Even those glorious attributes of God which are most terrible to the wicked, the saints with humble reverence rejoice in. And through faith in the atoning Sacrifice, we hope for greater honour than Moses ever enjoyed on earth. Now we see through a glass darkly, but when he shall appear, then face to face. This vision of God will continue with equal, if not increasing brightness of joy; not for a few days only, but through eternity.
