Israelites sojourned in Egypt

• Start — Genesis 47:9. The year Jacob (second-born son of Isaac) went to Egypt is his birth year (2170) + his age when he arrives and speaks to Pharaoh (130) = 2300
• End — Exodus 12:40. The year of the Exodus is the year of Abram was called (2085) + the years until the covenant (430) = 2515

START: END:

Years are anno hominis — counted from Creation as year 1 — which is the frame the source computes in. The arithmetic behind each boundary is given above rather than assumed.
