The land of Goshen is fascinating because it is much different from the Egypt that so many of us studied in elementary school. Instead of sand, river, and pyramids, Goshen is a flat agricultural region in the eastern Nile Delta.
Perhaps Goshen is most fascinating as the long-time home of the sons of Israel. Joseph told his brothers,
You shall dwell in the land of Goshen, and you shall be near me, you and your children and your children’s children, and your flocks, your herds, and all that you have. (Genesis 45:10 ESV)
The photo below shows reeds (bulrushes) growing on the banks of the Great Bitter Lake. This is the largest of a chain of lakes through which the Suez Canal runs. I have used a Photoshop plug-in called Topaz Adjust to turn this photo into a sketch that more resembles a photo made at night. If you think it might be useful in a lesson, you may click on the photo for a larger image.
There are several good suggestions for the place of the exodus recorded in Exodus 14. This vicinity may be the sea described in Exodus 14:9.
Then the Egyptians chased after them with all the horses and chariots of Pharaoh, his horsemen and his army, and they overtook them camping by the sea, beside Pi-hahiroth, in front of Baal-zephon.
Other scholars suggest a location associated with Lake Timsa which is a few miles to the north.
