In Moshe Rabeinu’s concluding words he prophecies that when the time for the redemption will come, the enemies of Israel will prevaricate about their circumstances.
“You are fortunate, Yisrael, who can compare to you-a people saved by Hashem, the shield of your aid who provides the victory of the sword of your glory; and your enemies will lie to you while you tread on their high places”. Rashi gives the example of the Givonites (they were residents of Eretz Yisrael but posed as visitors from a distant land to avoid attack by the Israelites) lieing to Bnei Yisrael at the time of Yehoshua. The Chasam Sofer says about Israel’s enemies, they make themselves as though they love you, and befriend you, but they still hate you.
They will cause Israel to let down its guard and then attack. An enemy that makes itself out to be your friend is more dangerous than an enemy that is open about its intentions. Despite this, the Chasam Sofer says that G-d Almighty will destroy them in their high places. The Bachor Shor says essentially the same thing as the Chasam Sofer. The Vilna Gaon relates each part of this Posuk to various times in Jewish History but the overriding message will be that this will apply in “future times”. He writes that “You are fortunate Yisrael” relates to Yehoshua crossing the Jordan River. He writes that “who can compare to you” refers to the times of King Solomon. He further states that “a people saved by Hashem” relates to Yehoshua’s conquest of Jericho and Hezekiah’s defeat of Sancheriv.
“The shield of your aid”, he says refers to Israel’s conquest of Yerushalayim and “who provides the victory of the sword of your glory” relates to the defeat of Haman. The Vilna Gaon continues that all will apply in “future times”. The State of Israel must know that our enemies will lie more and more the stronger the State of Israel gets. Their lies will increase proportional to Israel’s strength. After 4 major wars and 3 smaller wars since the State of Israel was founded in 1948 the Arabs are getting frustrated and are trying all kinds of new ways to defeat Israel.
