Ps.145
This chapter is missing a verse in the masoretic texts and the KJV bible.
The verse is found in all the "earlier" manuscripts. Each verse starts with a different letter of the Hebrew Alphabet (in order) but missing the "Nun". Following verse 13 the ancient texts reads:
"Faithful is YHVH in all His words And holy in all His works".
Present in The Septuagint, Syr., Vulgate, Arabic and Ethiopic texts. Why and how its missing from the masoretic texts I dont personally know at the moment. I dont know if the masoretic texts was damaged or if the verse was just skipped (for a "reason" or not).
