Exodus 24:18

Exo. 24:18. "And Moses was in the mount forty days and forty nights." Moses being so long in the mount with God when he received his mind and will to reveal to Israel, represents Christ's being in heaven with his Father to receive his mind and will to reveal to his church - his being from all eternity in the bosom of the Father; and it may be particularly forty days, because Christ came down from heaven, signified by this mount; it was four thousand years from the beginning of time, and from the creation and fall of man, and since the covenant of grace first took place, and Christ actually became the Mediator between God and man; which, putting ten for a thousand, and every age or century for a day, answers to forty days. That mount, when Moses was in it with God, typified heaven, as the apostle teaches, Hebrews 8:5.
