Psalm 99 is the 99th psalm of the Book of Psalms, beginning in English in the King James Version: "The LORD reigneth; let the people tremble". The Book of Psalms starts the third section of the Hebrew Bible, and, as such, is a book of the Christian Old Testament. In the slightly different numbering system in the Greek Septuagint version of the Bible, and in the Latin Vulgate, this psalm is Psalm 98, beginning "Dominus regnavit". It is the last of the set of additional Royal Psalms, praising God as King of his people. There is no title in the Masoretic Text version, but the Septuagint provides a title: "A psalm of David".
