This is the American Standard Version of the Bible. Published in 1901, the ASV emerged from the British efforts on the Revised Version. The ASV retains some of the Elizabethan wording of the King James Version. The ASV is popular with the Jehovah's Witnesses due to the use of Jehovah as the divine name in this translation.
The KJV is considered one of the masterpieces of early modern English literature, although most modern readers find the language a bit dated and occasionally opaque. There have been numerous successive English translations, many of which have borrowed heavily from the KJV.
