'By His Blood' in the Bible

[It is also] from Jesus Christ, who is the Faithful Witness [to the truth], the Firstborn from the dead [i.e., the first One raised never to die again], the Ruler of the kings of the world. May there be honor and power forever and ever to Christ, who loved us and released us from our sins by His blood [Note: Some manuscripts say "washed us" since the two words are spelled almost alike].
