Benjamin received his blessing in that the Beit HaMikdash (Temple) was built in his inheritance, and Judah began to possess the honor of the kingship.
Judah and Benjamin are two characteristics, two opposing forces, who shared in the birth of the people.
The layout, or general outline, of Egypt is reminiscent of the form of the uterus with a birth canal and the straits where the Israelis crossed the Red Sea. The forces that were sent after them by Pharaoh and which drove them forward symbolize the contractions in the uterus that push the fetus out.
