Numbers 1:44 These are the ones who were numbered, whom Moses and Aaron numbered, with the leaders of Israel, twelve men, each one representing his father’s house. 45 So all who were numbered of the children of Israel, by their fathers’ houses, from twenty years old and above, all who were able to go to war in Israel— 46 all who were numbered were six hundred and three thousand five hundred and fifty.
This number is in line with a 400-year sojourn in Egypt. This Scripture shows the number of Israelis to have been at least 2 million. They couldn't possibly have made THAT number of people in only 200 years!
