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 29 — A Psalm of David.
Give unto the LORD, O ye mighty, give unto the LORD glory and strength.
Give unto the LORD the glory due unto his name; worship the LORD in the beauty of holiness.
The voice of the LORD is upon the waters: the God of glory thundereth: the LORD is upon many waters.
The voice of the LORD is powerful; the voice of the LORD is full of majesty.
The voice of the LORD breaketh the cedars; yea, the LORD breaketh the cedars of Lebanon.
He maketh them also to skip like a calf; Lebanon and Sirion like a young unicorn.
The voice of the LORD divideth the flames of fire.
The voice of the LORD shaketh the wilderness; the LORD shaketh the wilderness of Kadesh.
The voice of the LORD maketh the hinds to calve, and discovereth the forests: and in his temple doth every one speak of his glory.
The LORD sitteth upon the flood; yea, the LORD sitteth King for ever.
The LORD will give strength unto his people; the LORD will bless his people with peace.
