However the translation reads. It’s obvious that it was Jesus blood that removed our sins from us NOT the water used at baptism.
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.

“Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others: For then must he often have suffered since the foundation of the world; but now once in the end of the world hath he appeared to PUT AWAY SIN BY THE SACRIFICE OF HIMSELF. And as it is appointed unto men once to die, but after this the judgement: So Christ was ONCE OFFERED to BEAR THE SINS OF MANY; and unto them that look for him shall he appear the second time without sin unto salvation.” Heb. 9:25-28.
