Hath set at naught (aqethsa). First aorist active participle of aqetew, late compound, very common in LXX, from alpha privative and tiqhmi, to render null and void, to set aside, only here in Hebrews (see Mark 7:9 ), but note aqethsi ( Hebrews 7:18 ; Hebrews 9:26 ). Without mercy (cwri oiktirmwn). See 2 Corinthians 1:3 . This was the law ( Deuteronomy 17:6 ) for apostates. On the word of two or three (epi dusin h trisin). "On the basis of two or three." For this use of epi with the locative see Deuteronomy 9:17 .
