What Does Exodus 24:1 Mean?

Then he said to Moses, "Come up to the LORD, you and Aaron, Nadab, and Abihu, and seventy of the elders of Israel, and worship from afar." Chapter 24 is the covenant's ratification chapter: the formal sealing of the Sinai covenant through blood-sprinkling, covenant meal, and Moses' prolonged mountain ascent to receive the tablets. The expanded covenant-group (Moses, Aaron, Nadab and Abihu, seventy elders) represents the full spectrum of Israel's covenant leadership: prophet, high priest, future priestly leaders, and the community's elder-representatives. All of Israel's leadership is summoned to the covenant's formal ratification.

The "seventy elders" is the full representative number: seventy as the number of completeness and representation (seventy nations in Genesis 10's Table of Nations; seventy members of Jacob's family who descended to Egypt in Genesis 46:27; the seventy elders appointed to help Moses judge in Numbers 11:16-25). The seventy representative leaders at Sinai's ratification create the full covenant-people-to-covenant-meal connection: when the seventy elders eat the covenant meal (verse 11), they eat as the whole community's representatives. The covenant sealed by the elders is Israel's covenant.

"Worship from afar": the staged approach (Moses full access, Aaron-and-sons closer access, elders worship from a distance, people at the mountain's base) is Sinai's graduated access structure applied to the covenant ratification ceremony. The same structure that governed the theophany preparation (people at foot, Moses at top) governs the ratification ceremony: proximity to YHWH is proportional to the degree of covenant representation held. The structure will be institutionalized in the tabernacle's court-holy-place-holy-of-holies architecture, where access is graduated the same way the Sinai mountain was graduated.
