Deuteronomy 1:29

לא תערצון — This is an expression denoting breaking, as the Targum translates it: You should not let yourselves be broken by them. Similar to it is, (Job 30:6) “To dwell in ערוץ נחלים”, i.e. in the fissure of the valleys.

וָאֹמַ֖ר אֲלֵכֶ֑ם לֹא־תַעַרְצ֥וּן וְלֹא־תִֽירְא֖וּן מֵהֶֽם׃

Then I said to you, Dread not, neither be afraid of them.
