Exodus 24:9-11

Young's Literal Translation

⁹ And Moses goeth up, Aaron also, Nadab and Abihu, and seventy of the elders of Israel,

¹⁰ and they see the God of Israel, and under His feet [is] as the white work of the sapphire, and as the substance of the heavens for purity;

¹¹ and unto those of the sons of Israel who are near He hath not put forth His hand, and they see God, and eat and drink.
