Codex Vaticanus (oldest full greek manuscript of the Bible)
Vulgate (St. Jerome)
Douay Rheims (Original translation from turn of the 17th century)
New Jerusalem (contemporary English)
In that order. I like to be able to track the translations so I can come to deeper understanding of the original text. Oddly enough, a single letter in one of the words in the Codex Vaticanus unfolded my understanding of the purpose for which John wrote his Gospel and the divine inspiration of St. Jerome when he translated the Greek text in reconciling the few small discrepancies in the Greek copies of the New Testament available to him at the time.
