So that upon your heads may come all the blood of the righteous ( those who correspond to the divine standard of right) shed on earth, from the blood of the righteous Abel to the blood of Zechariah son of Barachiah, whom you murdered between the sanctuary and the altar [of burnt offering].
[And] not be like Cain who [took his nature and got his motivation] from the evil one and slew his brother. And why did he slay him? Because his deeds (activities, works) were wicked and malicious and his brother's were righteous (virtuous).
The wicked lie in wait for the [uncompromisingly] righteous and seek to put them to death.
