Joshua 5:2

לְמַעַן דַּעַת כָּל־עַמֵּי הָאָרֶץ אֶת־יַד יְהוָה כִּי חֲזָקָה הִיא לְמַעַן יְרָאתֶם אֶת־יְהוָה אֱלֹהֵיכֶם כָּל־הַיָּמִֽים

that all the peoples of the earth may know the hand of the LORD, that it is mighty; that ye may fear the LORD your God for ever.’

וַיְהִי כִשְׁמֹעַ כָּל־מַלְכֵי הָאֱמֹרִי אֲשֶׁר בְּעֵבֶר הַיַּרְדֵּן יָמָּה וְכָל־מַלְכֵי הַֽכְּנַעֲנִי אֲשֶׁר עַל־הַיָּם אֵת אֲשֶׁר־הוֹבִישׁ יְהוָה אֶת־מֵי הַיַּרְדֵּן מִפְּנֵי בְנֵֽי־יִשְׂרָאֵל עַד־עברנו וַיִּמַּס לְבָבָם וְלֹא־הָיָה בָם עוֹד רוּחַ מִפְּנֵי בְּנֵֽי־יִשְׂרָאֵֽל

And it came to pass, when all the kings of the Amorites, that were beyond the Jordan westward, and all the kings of the Canaanites, that were by the sea, heard how that the LORD had dried up the waters of the Jordan from before the children of Israel, until they were passed over, that their heart melted, neither was there spirit in them any more, because of the children of Israel.

וַיַּעַשׂ־לוֹ יְהוֹשֻׁעַ חַֽרְבוֹת צֻרִים וַיָּמָל אֶת־בְּנֵי יִשְׂרָאֵל אֶל־גִּבְעַת הָעֲרָלֽוֹת

And Joshua made him knives of flint, and circumcised the children of Israel at Gibeath-ha-araloth.

וְזֶה הַדָּבָר אֲשֶׁר־מָל יְהוֹשֻׁעַ כָּל־הָעָם הַיֹּצֵא מִמִּצְרַיִם הַזְּכָרִים כֹּל אַנְשֵׁי הַמִּלְחָמָה מֵתוּ בַמִּדְבָּר בַּדֶּרֶךְ בְּצֵאתָם מִמִּצְרָֽיִם

And this is the cause why Joshua did circumcise: all the people that came forth out of Egypt, that were males, even all the men of war, died in the wilderness by the way, after they came forth out of Egypt.
