ציטירנדיקער פּירוש אויף יהושע 1:9

לערוץ To be mighty.²⁸A. V., To shake terribly. Root ערץ ; comp. עריץ mighty. According to others, it is a transitive verb, meaning to terrify; אל תערץ (Jos. 1:9) has, perhaps, the same meaning, the word לבך thine heart, being supplied—do not terrify or discourage thine heart—and עריץ (29:20), is then a transitive adjective, terrible, like אימים (Gen. 14:5), the terrifying ones.²⁹A.V., The Emims.
