"Then after [another] forty years passed, an angel appeared to him [one day] out of a flaming bush in the wilderness near Mt. Sinai.

This is the man who was with our forefathers and with the assembly [of Hebrews] in the wilderness [after] the angel had spoken to him at Mt. Sinai. He [is the one] who received the living messages [from God at Mt. Sinai] and gave them to us.
