In spring all creatures came into being and the first parent was formed from the clay of the earth. In spring Jacob was called from Mesopotamia to his own land. In spring the children of Israel were led out of the land of Egypt, the blood of the lamb turned the destroyer of Egypt away, and they entered the promised land after crossing the Jordan. In spring Christ our Redeemer, ascending by the example of his death from the valley of tears to the mountain of Paradise, summons the church, saying: Arise, hasten, my love, my lovely one, and come, for winter is past.
