The Book of Psalms is canonical in Judaism (Ketuvim) and Christianity (Old Testament), with its authority confirmed by ancient manuscripts (Qumran), the New Testament, and councils (Hippo, Carthage). The Ethiopian Orthodox Tewahedo Church, however, has a broader canon that includes Psalm 151 as an integral part of the Psalter, accepted as Holy Scripture also by Orthodox, Syriac, and Armenian traditions, demonstrating the historical diversity of biblical canons.
Psalms
Chapter 96
O sing unto the LORD a new song: sing unto the LORD, all the earth.
Sing unto the LORD, bless his name; shew forth his salvation from day to day.
Declare his glory among the heathen, his wonders among all people.
For the LORD is great, and greatly to be praised: he is to be feared above all gods.
For all the gods of the nations are idols: but the LORD made the heavens.
Honour and majesty are before him: strength and beauty are in his sanctuary.
Give unto the LORD, O ye kindreds of the people, give unto the LORD glory and strength.
Give unto the LORD the glory due unto his name: bring an offering, and come into his courts.
O worship the LORD in the beauty of holiness: fear before him, all the earth.
Say among the heathen that the LORD reigneth: the world also shall be established that it shall not be moved: he shall judge the people righteously.
Let the heavens rejoice, and let the earth be glad; let the sea roar, and the fulness thereof.
Let the field be joyful, and all that is therein: then shall all the trees of the wood rejoice
Before the LORD: for he cometh, for he cometh to judge the earth: he shall judge the world with righteousness, and the people with his truth.
