Deuteronômio 9

Deuteronômio 9:9

This is why Moses fasted for forty days, and Elijah, and the Mediator himself, our Lord Jesus Christ: because in this time-bound state of ours restraint from bodily attractions and allurements is very necessary. The people also spent forty years wandering in the desert, and forty days of rain produced the flood. The Lord spent forty days after his resurrection with his disciples, to convince them of the reality of his risen body. This suggests that in this life, in which we are in exile away from the Lord, the number forty stands, as I have just said, for our need to celebrate the memorial of the Lord's body, which we do in the church until he comes. — Sermon 51.32
