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 128 — A Song of degrees.
Blessed is every one that feareth the LORD; that walketh in his ways.
For thou shalt eat the labour of thine hands: happy shalt thou be, and it shall be well with thee.
Thy wife shall be as a fruitful vine by the sides of thine house: thy children like olive plants round about thy table.
Behold, that thus shall the man be blessed that feareth the LORD.
The LORD shall bless thee out of Zion: and thou shalt see the good of Jerusalem all the days of thy life.
Yea, thou shalt see thy children's children, and peace upon Israel.
