The Egyptians worshipped false gods who as they fancied managed the seasons and the weather. God sent them thunder and hail when it pleased Him, and showed the Jews that _He_, not these false gods of Egypt, ruled the heavens. The Egyptians and many other heathen nations of the earth used to offer their children to false gods. I do not mean by killing them in sacrifice, but by naming them after some idol, and then expecting that the idol would ever afterwards prosper and strengthen them. Thus the kings were called after the sun. Pharaoh means the Sun-king; for they fancied that the sun was a god, and protected their kings one after the other. And God slew all the first-born of Egypt, even the first-born of King Pharaoh on his throne. The Sun-god could not help him. The idols of Egypt could not take care of their worshippers--only the children of the Jews escaped. (Exodus xii.) What a lesson for the Jews! And they needed it; for during the four hundred years that they had been in Egypt they had almost forgotten the one true God, the God of their forefathers, Abraham, Isaac and Jacob; at least they thought Him no better than the false gods of Egypt. After all these wondrous proofs of God's almighty power, and His jealousy for His own name, they fell away to idols again and again. They worshipped a golden calf in Horeb (Exodus xxxii.); they turned aside to worship the idols of the nations whom they passed through on their way to Canaan. Idolatry had been rooted in their hearts, and it took many years of severe training and teaching on God's part to drive it out of them--to make them feel that the one God, who made heaven and earth, had delivered them--that they belonged to Him, that they had a share in Him--to make them join with one heart and voice in the glorious song of Moses:
