Exodus 24:9-11

Then Moses, Aaron, Nadab, and Abihu, and seventy of the elders of Israel went up [the mountainside], and they saw [a manifestation of] the God of Israel; and under His feet there appeared to be a pavement of sapphire, just as clear as the sky itself. [Ex 33:20-23; Deut 4:12; Ezek 28:14] Yet He did not stretch out His hand against the nobles of the Israelites; and they saw [the manifestation of the presence of] God, and ate and drank. [Ex 19:21]
