Sinai is the wilderness walked through by the Sons of Israel on their way to Mount Sinai. The Sinai wilderness and Mount Sinai are mentioned 35 times in the Old Testament.
Sinai was assaulted in 1956 and then in 1967, after which the land was liberated in 1973 and the Israeli people went back to where they came from. Each year Egypt celebrates the liberation of all the land of Sinai, when President Mubarak raises the flag on the farthest point in Sinai, which is Taba.
