sometimes the notes help to clear things up.
Rev 1:5 (KJV)
And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,
Rev 1:5 (ASV)
and from Jesus Christ, who is the faithful witness, the firstborn of the dead, and the ruler of the kings of the earth. Unto him that loveth us, and loosed us from our sins by his blood; (Many authorities, some ancient, read washed. Hebrews 9:14; compare chapter revelation 7:14.)
Rev 1:5 (ESV2011)
and from Jesus Christ the faithful witness, the firstborn of the dead, and the ruler of kings on earth. To him who loves us and has freed us from our sins by his blood
Rev 1:5 (HCSB)
and from Jesus Christ, the faithful witness, the firstborn from the dead and the ruler of the kings of the earth. To Him who loves us and has set us free from our sins by His blood, (1:5 Other mss read has washed us)
Rev 1:5 (NET)
and from Jesus Christ – the faithful witness, the firstborn from among the dead, the ruler over the kings of the earth. To the one who loves us and has set us free from our sins at the cost of his own blood
( Rev 1:5 (NET Notes)
3 tc The reading “set free” (λύσαντι, lusanti) has better ms support (Ì18 א A C 1611 2050 2329 2351 ÏA sy) than its rival, λούσαντι (lousanti, “washed”; found in P 1006 1841 1854 2053 2062 ÏK lat bo). Internally, it seems that the reading “washed” could have arisen in at least one of three ways: (1) as an error of hearing (both “released” and “washed” are pronounced similarly in Greek); (2) an error of sight (both “released” and “washed” look very similar – a difference of only one letter – which could have resulted in a simple error during the copying of a ms); (3) through scribal inability to appreciate that the Hebrew preposition ב can be used with a noun to indicate the price paid for something. Since the author of Revelation is influenced significantly by a Semitic form of Greek (e.g., 13:10), and since the Hebrew preposition “in” (ב) can indicate the price paid for something, and is often translated with the preposition “in” (ἐν, en) in the LXX, the author may have tried to communicate by the use of ἐν the idea of a price paid for something. That is, John was trying to say that Christ delivered us at the price of his own blood. This whole process, however, may have been lost on a later scribe, who being unfamiliar with Hebrew, found the expression “delivered in his blood” too difficult, and noticing the obvious similarities between λύσαντι and λούσαντι, assumed an error and then proceeded to change the text to “washed in his blood” – a thought more tolerable in his mind. Both readings, of course, are true to scripture; the current question is what the author wrote in this verse.)
Rev 1:5 (SLT)
And from Jesus Christ, the faithful witness, the first born from the dead, and the chief of the kings of the earth. To him having loved us, and washed us from our sins in his blood,
Rev 1:5 (YLT)
and from Jesus Christ, the faithful witness, the first-born out of the dead, and the ruler of the kings of the earth; to him who did love us, and did bathe us from our sins in his blood,
