Q: When do you think the 430 year sojourn began? Did it begin with the promise made to Abraham in Genesis 12:1-7, or when the promise was confirmed to Jacob on the way to Egypt in Genesis 46:3 (the idea being that the children of Israel were in Egypt for 30 years before the start of 400 years of affliction)? In Dr. Cooper's book “Messiah, His First Coming Scheduled” pages 129 to 135, it states that the children of Israel were in Egypt for only 215 years. Do you agree with Dr. Cooper's position? Which position is correct?

A: I think the best way to count off the 430 years would be to begin with the official day of the weaning of Isaac in Genesis 21:8. I would agree that the period of sojourning was not just in Egypt but included the sojourning in both the Land and in Egypt and I would agree the Egyptian sojourning was closer to 215 years.

So I agree with what you read in the work by Dr. Cooper on that point.
