Yom Yerushalayim - 40 Years - Essay Question

This year, on Yom Yerushalayim, we will be celebrating 40 years of Jewish sovereignty over the holy city of Jerusalem.
I did a search through Tana"ch, and here is a list of occurrances that the Torah mentions "ארבעים שנה":

• Yitzhak's age when he married Rivka
• Eisav's age when he married
• Duration of Israelites' journey in the desert
• Duration of Otni'el's reign as judge
• Duration of Devorah Haneviah's reign as judge
• Duration of Gideon's reign as judge
• Duration of the Israelites in the hands of Pelishtim before Shimshon
• Duration of Eili Hakohen's reign as judge
• Ish Boshet's age when he became king
• Duration of David's reign as king
• Beginning of Avshalom's rebellion (Shemu'el II 15:7)
• Duration of Shelomo's reign as king
• Duration of Yeho'ash's reign as king
