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 123 — A Song of degrees.
Unto thee lift I up mine eyes, O thou that dwellest in the heavens.
Behold, as the eyes of servants look unto the hand of their masters, and as the eyes of a maiden unto the hand of her mistress; so our eyes wait upon the LORD our God, until that he have mercy upon us.
Have mercy upon us, O LORD, have mercy upon us: for we are exceedingly filled with contempt.
Our soul is exceedingly filled with the scorning of those that are at ease, and with the contempt of the proud.
