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 67 — To the chief Musician on Neginoth, A Psalm or Song.
God be merciful unto us, and bless us; and cause his face to shine upon us; Selah.
That thy way may be known upon earth, thy saving health among all nations.
Let the people praise thee, O God; let all the people praise thee.
O let the nations be glad and sing for joy: for thou shalt judge the people righteously, and govern the nations upon earth. Selah.
Let the people praise thee, O God; let all the people praise thee.
Then shall the earth yield her increase; and God, even our own God, shall bless us.
God shall bless us; and all the ends of the earth shall fear him.
