Many today dispute the story of the Exodus, but Jesus didn’t, and I’d believe Him anytime.
Can you imagine the scene! We’re told there were “about six hundred thousand men on foot” (Ex 12:37) plus the women and children, the aged, and Levites—perhaps two-and-a-half to three million people. In addition, “a mixed multitude went up with them also, and…a great deal of livestock” (v 38). This “mixed multitude” may have included non-Hebrews who took advantage of the situation, and even believing Egyptians we read of earlier, “who feared the word of the Lord among the servants of Pharaoh” (9:20). In any case, what a sight it must have been! They left behind the city of Rameses, near their land of Goshen, and slowly headed east. Of course, they had made some preparation: “they baked unleavened cakes of the dough which they had brought out of Egypt” (12:39), but it was minimal. The manifesting of God’s supernatural power was essential to convince the heads of the families to follow Him into a vast desert with their wives and children and livestock. No hotels, no restaurants, and millions of mouths to feed! At this point in the narrative we are told, “Now the sojourn of the children of Israel who lived in Egypt was four hundred and thirty years” (v 40). Many commentators say this is impossible, but the apostle Paul both concurs and clarifies: “Now to Abraham and his Seed were the promises made…And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ” (Gal 3:16-17). Thus the whole span is being measured, from God’s promise to Abraham, that his progeny would be held in Egypt but eventually return, until the national covenant was ratified at Sinai. The Bible is its own best commentary, and you can trust God’s Word.
