Cast not away therefore your boldness (mē apobalēte oun tēn parrēsian humōn). Prohibition with mē and the second aorist active subjunctive of apoballō. Old verb to throw away from one as worthless, only twice in the N.T., here in a figurative sense and Mar 10:50 in a literal sense (garment by Bartimaeus). The Jewish Christians in question were in peril of a panic and of stampeding away from Christ. Recall katechōmen in Heb 10:23.
