Bart D. Ehrman says this was a corrupt reading from a proto-orthodox scribe, although this conclusion has not gained wide support. For most of the New Testament, "Codex Sinaiticus" is in general agreement with "Codex Vaticanus Graecus 1209" and "Codex Ephraemi Rescriptus", attesting the Alexandrian text-type. A notable example of an agreement between the Sinaiticus and Vaticanus texts is that they both omit the word εικη ('without cause', 'without reason', 'in vain') from Matthew 5:22 ""But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgement"". In John 1:1–8:38 "Codex Sinaiticus" differs from Vaticanus and all other Alexandrian manuscripts. It is in closer agreement with "Codex Bezae" in support of the Western text-type. For example, in John 1:4 Sinaiticus and Codex Bezae are the only Greek manuscripts with textual variant ἐν αὐτῷ ζωὴ ἐστίν ("in him is life") instead of ἐν αὐτῷ ζωὴ ᾓν ("in him was life"). This variant is supported by Vetus Latina and some Sahidic manuscripts. This portion has a large number of corrections. There are a number of differences between Sinaiticus and Vaticanus; Hoskier enumerated 3036 differences:  A large number of these differences are due to iotacisms and variants in transcribing Hebrew names. These two manuscripts were not written in the same scriptorium. According to Fenton Hort "Sinaiticus" and "Vaticanus" were derived from a common original much older source, "the date of which cannot be later than the early part of the second century, and may well be yet earlier". Example of differences between Sinaiticus and Vaticanus in Matt 1:18–19:  B. H. Streeter remarked a great agreement between the codex and Vulgate of Jerome. According to him, Origen brought to Caesarea the Alexandrian text-type that was used in this codex, and used by Jerome. Between the 4th and 12th centuries, seven or more correctors worked on this codex, making it one of the most corrected manuscripts in existence.
