... in your opinion. But throughout the OT (as the NT) the natural always came before the spiritual. This dynamic of Jacob and Israel fits in with that. Hebrew blood, the promises to Abraham, are embodied in the creation of Israel.
After Jacob’s encounter with God at Peniel, his name was changed to Israel. Here was the beginning of Israel’s story, albeit Israel didn’t take on a more formal nationalistic character until Moses. Jacob had 12 children, these became the literal children of Israel. From this Israel developed. His children were: Reuben, Simeon, Levi, Judah, Issachar, Zebulun, Benjamin, Dan, Naphtali, Gad, Asher and Joseph. These became the 12 tribes of Israel. When it came to receiving land, the tribe of Levi was not assigned land, as they were set aside to serve the Lord. The allocation of land was thus distributed: Reuben, Simeon, Judah, Issachar, Zebulun, Benjamin, Dan, Naphtali, Gad, Asher, Ephraim and Manasses. The tribe of Joseph was basically split into 2 – Ephraim and Manasses. Jacob became the patriarch of this new evolving people-group.
Israel was an evolving organism. As time moved along in Egypt, and as the Pharoah’s changed, Egypt became more and more concerned at the strength and influence of the Israelites. When they arrived in Egypt, they were a family of 70 (Exodus 1:5 and Deuteronomy 10:22). By the time they exited Egypt, they were a significant ethnic group, numbering millions. Even though we do not know an exact figure, we can assume that because the size of Israel’s army (post-exodus) numbered well over 600,000 men (Numbers 1:17–46). Some learned historians suggest this figure implies a total Israelite population of around 2.4 million. Most theologians and historians estimate Israel’s population to have been around 3 million.
After the children of Israel’s prolonged sojourn in Egypt, and with God’s raising up of a strong leader to head up the Hebrew people in Moses, Israel took on a more nationalistic form. God raised up Moses to deliver His people from the bondage of Egypt and the cruelty of Pharaoh. He became God’s chosen instrument to preserve His seed and oversee His flock. Hebrews 3:2 sums up the character of Israel’s deliverer: “Moses was faithful in all his house.”
As with any new nation, there was a need to organize it into a healthy viable structure with suitable laws to govern it. From Egypt, the Israelites were led by God to Mount Sinai, who appeared throughout their travels as a cloud by day and as a fire by night (Exodus 13:21). It was here that Moses spoke directly with God and received the Ten Commandments, which were strict guidelines by which He required the nation of Israel to abide by. These laws were God’s blueprint for ruling Israel direct from heaven.
