The Four Hundred and Thirty years
The four hundred and thirty years are mentioned in Genesis 15. Abram wondered how much longer he would have to remain a stranger in the Land of Promise, and if he would ever see the fulfillment of God’s promises. The Lord therefore revealed the answer to him saying: “Know certainly that your descendants will be strangers in a land that is not theirs, and will serve them, and they will afflict them four hundred years” (Genesis 15:13).
There are two questions that need to be answered here: Are the four hundred years the time of affliction or the time of sojourning, or both? Are the four hundred years related to the four hundred and thirty years of Exodus 12:40, 41 and Galatians 3:16, 17?
In Exodus 12:40, “the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years.” This suggests that the Israelites did spend four hundred and thirty years there, from Jacob’s entry to the Exodus. That this cannot be the meaning is clear from Galatians 3:16, 17, where it is said that the law was made public at Sinai four hundred and thirty years after the covenant between God and Abram.
If Paul refers to the first promise made to Abram in Haran (Genesis 12:1–3), the four hundred and thirty years began when Abram was seventy-five years old (Genesis 12:4). The four hundred years of affliction would then begin thirty years later, when Abram was one hundred and five and his son Isaac five years old (Genesis 21:5). This would be about the time Ishmael, who “was born after the flesh persecuted him [Isaac] that was born after the Spirit” (Galatians 4:29; Genesis 21:9–11).
The precise time from the call of Abram to Jacob’s entrance into Egypt was two hundred and fifteen years (Genesis 21:5; 25:26; 47:9), which would leave two hundred and fifteen years of the four hundred and thirty as the real time the Hebrews spent there.
Therefore, the four hundred and thirty years of Exodus 12:40 must encompass the sojourn in Canaan as well as that in Egypt, from Abram’s call to the Exodus. The LXX (the Septuagint) show Exodus 12:40 thus: “And the sojourning of the children of Israel, while they sojourned in the land of Egypt and the land of Canaan, was four hundred and thirty years.”
As shown before, the land of Canaan relied greatly upon Egypt during the patriarchal era that the Egyptian kings regarded it as theirs. During the Eighteenth Dynasty, whose kings ruled both Palestine and Syria, Moses could accurately encompass Canaan in the term Egypt as used in Exodus 12:40.
Genesis 15:16 says, “But in the fourth generation they shall return here, for the iniquity of the Amorites is not yet complete.” Bible Commentators, who apply the four hundred years of Genesis 15:13 to the actual time the Hebrews lived in Egypt, face a problem. They must suppose that the four generations averaged exactly hundred years each.
But this is opposing to available proof. However, since the four hundred years of verse 13 must refer to the time from Abram to the Exodus (verse 13), and the actual time of Israel’s remaining in Egypt was only two hundred and fifteen years, no inconsistency exists between this prophecy and its fulfillment. Caleb was part of the fourth generation from Judah (1 Chronicles 2:3–5, 18), and Moses, from Levi (Exodus 6:16–20). Efforts to determine the length of a “generation” based on Genesis 15:13, 16 are unreasonable, and the outcomes are deceptive. One “generation,” went into Egypt, two lived there, and the fourth left.
