From Egypt to Sinai.
Ex. Chs. 1-19 Israel in Egypt. The length of time the Hebrews remained In Egypt is a perplexing question. Exodus 6:16-20 makes Moses the fourth generation from Levi (See Gen. 15:16; Num. 26:57-59). This would make it about 150 years. Gen. 15:13 predicts 400 years. Ex. 12:40 says they were there 430 years and Paul (Gal. 3:17) says 430 years from Abraham to Sinai.

Exodus
The book of Exodus--so named in the Greek version from the march of Israel out of Egypt--opens upon a scene of oppression very different from the prosperity and triumph in which Genesis had closed. Israel is being cruelly crushed by the new dynasty which has arisen in Egypt (i.) and the story of the book is the story of her redemption. Ultimately it is Israel's God that is her redeemer, but He operates largely by human means; and the first step is the preparation of a deliverer, Moses, whose parentage, …
