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 93
The LORD reigneth, he is clothed with majesty; the LORD is clothed with strength, wherewith he hath girded himself: the world also is stablished, that it cannot be moved.
Thy throne is established of old: thou art from everlasting.
The floods have lifted up, O LORD, the floods have lifted up their voice; the floods lift up their waves.
The LORD on high is mightier than the noise of many waters, yea, than the mighty waves of the sea.
Thy testimonies are very sure: holiness becometh thine house, O LORD, for ever.
