Revelation 2:23

Amplified Bible, Classic Edition

²³ And I will strike her children (her proper followers) dead [thoroughly exterminating them]. And all the assemblies (churches) shall recognize and understand that I am He Who searches minds (the thoughts, feelings, and purposes) and the [inmost] hearts, and I will give to each of you [the reward for what you have done] as your work deserves.^(A)
