'Sins' in the Bible

and from Jesus the Messiah, the witness, the faithful one, the firstborn from the dead, and the ruler over the kings of the earth. To the one who loves us and has freed us from our sins by his blood

Then another angel, a second one, followed him, saying, "Fallen! Babylon the Great has fallen! She has made all nations drink the wine, the wrath earned for her sexual sins."

Then I heard another voice from heaven saying, "Come out of her, my people, so that you don't participate in her sins and also suffer from her diseases.

For her sins are piled as high as heaven, and God has remembered her crimes.
