If someone came along and set down two copies of the Bible and told you that both are an accurate and faithful translation of the original but one has twenty percent extra words; you would be forgiven for seriously doubting their claims. It is simply not possible that both could be accurate and faithful when one has so many extra words. How much more is your credulity stretched to breaking point when this is true about one psalm, albeit, the longest of psalms, never mind all 150 psalms?
There are many extra words in the metrical version of the Psalms that have no corresponding word in the Hebrew original. At least when the Authorised Version does this, to assist the readability of the English translation, the translators put the additional words in italics. If you followed this practice with the metrical version you would have no end of words in italics. On average every third word in Psalm 119 of the metrical version and this is in addition to those which the Authorised Version places in italics.
