Psalm 145 is the 145th psalm of the Book of Psalms, generally known in English by its first verse, in the King James Version, "I will extol thee, my God, O king; and I will bless thy name for ever and ever". In Latin, it is known as "Exaltabo te Deus meus rex". It is the last psalm in the final Davidic collection of psalms, comprising Psalms 138 to 145, which are specifically attributed to David in their opening verses. In the slightly different numbering system used in the Greek Septuagint version of the Bible, and in the Latin Vulgate, this psalm is Psalm 144. The psalm is a hymn psalm. The psalm forms a regular part of Jewish, Catholic, Lutheran, Anglican and other Protestant liturgies. It has often been set to music, notably by Antonín Dvořák who set several verses in Czech in his Biblical Songs. Background and themes This is the only psalm which identifies itself as a תְּהִלָה (tehillah) – as a psalm (namely, a hymn of praise). The version in the Dead Sea Scrolls instead describes itself as a "prayer" although it does not contain any request. Psalm 145 is an alphabetic acrostic, the initial letter of each verse being the Hebrew alphabet in sequence. For this purpose, the usual Hebrew numbering of verse 1, which begins with the title, "A Psalm of David", is ignored in favor of the non-Hebrew numbering which treats verse 1 as beginning ארוממך (Aromimkha, "I will exalt You"). The Dead Sea Scrolls version also ends each verse with the recurring (non-canonical) refrain, "Blessed be YHVH and blessed be His name forever and ever" and adds at the end of the Psalm the tag, "This is for a memorial". The Dead Sea Scrolls version also preserves a line beginning with the letter nun. Psalm 145 is the last Psalm attributed explicitly to David, and also the last of the nine acrostic Psalms in its placement in the Book of Psalms (the acrostic Psalms being Psalms 9, 10, 25, 34, 37, 111, 112, 119 and 145). Methodist writer Joseph Benson notes that the king (David) praises "his king", "termed so by way of eminence: the King of kings, the God by whom kings reign".
