Throughout Rav Hirsch's commentary on the Torah we find a deeper connection between related words. (i.e. Vayikra (5:15) "מַעַל is related to the me’il – robe of the Kohen gadol – as begged “garment” is related to bagad “faithless”.) Therefore, what is the inherent connection between the number five in relation to being armed Shemos (13:18) seen below?
Mechon translates (Shemos 13:18):
וַיַּסֵּב אֱלֹהִים אֶת-הָעָם דֶּרֶךְ הַמִּדְבָּר, יַם-סוּף; וַחֲמֻשִׁים עָלוּ בְנֵי-יִשְׂרָאֵל, מֵאֶרֶץ מִצְרָיִם. "But God led the people about, by the way of the wilderness by the Red Sea; and the children of Israel went up armed out of the land of Egypt."
Note: I'm not looking for the Rashi quoted here that "'chamushim' is from the root 'chamaish'- 5 showing only 1/ 5 of the Jews came out of Egypt. Or the Targum Yonasan ben Uziel who writes "Chamushim stems from the root 'chamaish'- that each family left Egypt with 5 kids!" What is the inherent connection between 5 and being armed?
