Judg 7:12

וּמִדְיָ֨ן וַעֲמָלֵ֤ק וְכָל־בְּנֵי־קֶ֨דֶם֙ נֹפְלִ֣ים בָּעֵ֔מֶק כָּאַרְבֶּ֖ה לָרֹ֑ב וְלִגְמַלֵּיהֶם֙ אֵ֣ין מִסְפָּ֔ר כַּח֛וֹל שֶׁעַל־שְׂפַ֥ת הַיָּ֖ם לָרֹֽב׃

Now the Midianites, Amalekites, and all the other people of the east had settled in the valley like a swarm of locusts, and their camels were as countless as the sand on the seashore.
