from the blood of Abel to the blood of Zechariah, who perished between the altar and the sanctuary. Yes, I tell you, it shall be required of this generation.
And you shall say to them, ‘This is the nation that did not obey the voice of the Lord their God, and did not accept discipline; truth has perished; it is cut off from their lips.
that upon you may come all the righteous blood shed on earth, from the blood of innocent Abel to the blood of Zechariah the son of Barachiah, whom you murdered between the sanctuary and the altar.
By faith Abel offered to God a more acceptable sacrifice than Cain, through which he received approval as righteous, God bearing witness by accepting his gifts; he died, but through his faith he is still speaking.
and not be like Cain who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.
