Exodus 24:10 And they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.

Exodus 24:10 and they saw the God of Israel; and under His feet there appeared to be a pavement of sapphire, as clear as the sky itself.

10. And they saw the God of Israel--That there was no visible form or representation of the divine nature, we have expressly intimated (De 4:15). But a symbol or emblem of His glory was distinctly, and at a distance, displayed before those chosen witnesses. Many think, however, that in this private scene was discovered, amid the luminous blaze, the faint adumbrated form of the humanity of Christ (Eze 1:26; compare Ga 3:24).
sapphire--one of the most valuable and lustrous of the precious gems--of a sky-blue or light azure color and frequently chosen to describe the throne of God (see Eze 1:26; 10:1).

Exodus 24 Images and Notes

Brief Summary: Moses, as mediator between God and Israel, having received divers laws and ordinances from God privately in the three foregoing chapters, in this chapter, I. Comes down to the people, acquaints them with the laws he had received, and takes their consent to those laws (v. 3), writes the laws, and reads them to the people, who repeat their consent (v. 4-7), and then by sacrifice, and the sprinkling of blood, ratifies the covenant between them and God (v. 5, v. 6, v. 8). II. He returns to God again, to receive further directions. When he was dismissed from his former attendance, he was ordered to attend again (v. 1, v. 2). He did so with seventy of the elders, to whom God made a discovery of his glory (v. 9-11). Moses is ordered up into the mount (v. 12, v. 13); the rest are ordered down to the people (v. 14). The cloud of glory is seen by all the people on the top of mount Sinai (v. 15-17), and Moses is therewith God forty days and forty nights (v. 18).
