Bede, on 1Pet 2:9

“But you are a chosen generation, a kingly priesthood, a holy nation, a purchased people: that you may declare his virtues, who hath called you out of darkness into his marvellous light:”

“That you may declare His virtues, etc. For just as those who were freed from Egyptian bondage through Moses sang a triumphal song to the Lord after the crossing of the Red Sea and the drowning of Pharaoh's army, so it is also proper for us, after receiving in baptism the remission of sins, to repay worthy thanks for heavenly benefits. For the Egyptians, who afflicted the people of God, and who are also interpreted as darkness or tribulations, aptly signify our sins, which are erased in baptism. The liberation of the children of Israel and their leading to the promised homeland aligns with the mystery of our redemption, through which we strive towards the light of the heavenly dwelling place, illuminated and guided by the grace of Christ. The light of this grace was also shown by the pillar of cloud and fire, which protected them from the darkness of the nights throughout their entire journey and led them on an indescribable path to the promised homeland's seats.”
