Bible Verses About Righteousness: Slay those who follow

The wicked is watching for the righteous, And is seeking to put him to death.

that on you may come all the righteous blood being poured out on the earth from the blood of Abel the righteous, unto the blood of Zacharias son of Barachias, whom ye slew between the sanctuary and the altar:

not as Cain--of the evil one he was, and he did slay his brother, and wherefore did he slay him? because his works were evil, and those of his brother righteous.
