Matthew 5:38-40
"You have heard what was said [Exodus 21:24], 'Take an eye [from someone] if he takes yours, and take a tooth [from someone] if he takes yours.'
Matthew 7:2
For the way you judge [other people] is the way you [yourselves] will be judged. And the standard you use [for dealing] with others is the standard that they [and God] will use on you.
Luke 6:38
Give [to others] and you will have [things] given to you. People will pour into your lap a full measure [of goods]; it will be pressed down, shaken together and running over [the edges]. Because the standard you use in giving [to others] will be the standard used [by them or God] in giving back to you."
Revelation 16:6
For they [i.e., the followers of the beast. See verse 2] have shed the blood of God's holy people and [their] prophets, and you have given them blood to drink because they deserved it [i.e., these persecutors deserved the punishment they received for shedding blood].
