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 97
The LORD reigneth; let the earth rejoice; let the multitude of isles be glad thereof.
Clouds and darkness are round about him: righteousness and judgment are the habitation of his throne.
A fire goeth before him, and burneth up his enemies round about.
His lightnings enlightened the world: the earth saw, and trembled.
The hills melted like wax at the presence of the LORD, at the presence of the Lord of the whole earth.
The heavens declare his righteousness, and all the people see his glory.
Confounded be all they that serve graven images, that boast themselves of idols: worship him, all ye gods.
Zion heard, and was glad; and the daughters of Judah rejoiced because of thy judgments, O LORD.
For thou, LORD, art high above all the earth: thou art exalted far above all gods.
Ye that love the LORD, hate evil: he preserveth the souls of his saints; he delivereth them out of the hand of the wicked.
Light is sown for the righteous, and gladness for the upright in heart.
Rejoice in the LORD, ye righteous; and give thanks at the remembrance of his holiness.
