So that your generations shall know that I caused the sons of Israel to dwell in tents in my bringing them out of the land of Egypt: I Jehovah your God.
And it will be from the end of thirty years and four hundred years, in this self-same day all the armies of Jehovah will go forth out of the land of Egypt
And it was when thy son shall ask thee to-morrow, saying, What this? and thou saidst to him, With strength of hand Jehovah brought us forth out of Egypt from the house of servants.
