The angel of the Lord found Hagar near a spring in the desert; it was the spring that is beside the road to Shur.
Genesis 16:7 (NIV)
After being afflicted by Sarai, Hagar the Egyptian woman flees and is met by the angel at a spring near the road to Shur.
The road to Shur is the path back to Egypt. Sarai’s actions led Hagar to want to return to her old life. Back to destruction. Back to the idols of Egypt.
Then Moses led Israel from the Red Sea and they went into the Desert of Shur. For three days they traveled in the desert without finding water.
Exodus 15:22 (NIV)
The road to Shur leads to the Desert of Shur. It should be considered miraculous to flee Egypt by way of it. It should be considered certain death to travel back to Egypt through it.
That the people of God would make Hagar flee into certain death is a great shame.
