And when he opened the chotam hachamishi (fifth seal), I saw underneath the Mizbe'ach (altar) the nefashot (souls) of the ones having died al kiddush ha-Shem, having been slain as martyrs because of the dvar Hashem (word of G-d) and because of their solemn eidus (testimony) which they had given. [SHEMOT 29:12; VAYIKRA 4:7]
