Did Israel leave Egypt exactly 430 years to the day?
Yes. Scripture's timeline is exact: the 430 years ended on the precise day Israel departed Egypt. God's control of time and events is complete, missing the appointed year by not even twenty-four hours. The exodus occurred on the exact day the 430 years concluded.
Les explains that God is in such complete control of time and events that He does not miss the 430 years by even twenty-four hours. The exact day the 430 years ended, Israel moved out of Egypt. This follows the night of the Passover and Pharaoh letting the people go. God did not lead them through the way of the Philistines, the shorter route, but they came out of Goshen and down the shore of the Red Sea, where they would be locked in with mountains nearby.
