Why 69 holocoust museums?
Perhaps because Egypt in scripture speaks of the corrupt world system. When Israel came down into Egypt he brought with him his family of 69 souls. So the total number of offspring was 70, but one son, Joseph, was there already. Joseph was Pharoahs right hand so to speak, he ruled all the land, and these 70 grew into a multitude which controlled Egypt at the hand of Joseph. If museums/memorials represent the 69 that came into the world system, then there must be a 70th which was set up before all these other 69. (The state of Israel itself.) I’m not saying this is so, but there is a pattern to everything.
Now I can go on and tell about how when this family came out of Egypt after 430 years they were corrupt at that time of coming out and consumed in the wilderness by the Lord. So that generation that came out was not the same generation that inherited the promised land.
