Bible Verses About Righteousness: Slay those who follow

Though the wicked lie in wait for the righteous, and seek to slay them,

And so upon you will come all the righteous blood shed on earth, from the blood of righteous Abel to the blood of Zechariah son of Berechiah, whom you murdered between the temple and the altar.

Do not be like Cain, who belonged to the evil one and murdered his brother. And why did Cain slay him? Because his own deeds were evil, while those of his brother were righteous.
