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 11 — To the chief Musician, A Psalm of David.
In the LORD put I my trust: how say ye to my soul, Flee as a bird to your mountain?
For, lo, the wicked bend their bow, they make ready their arrow upon the string, that they may privily shoot at the upright in heart.
If the foundations be destroyed, what can the righteous do?
The LORD is in his holy temple, the LORD's throne is in heaven: his eyes behold, his eyelids try, the children of men.
The LORD trieth the righteous: but the wicked and him that loveth violence his soul hateth.
Upon the wicked he shall rain snares, fire and brimstone, and an horrible tempest: this shall be the portion of their cup.
For the righteous LORD loveth righteousness; his countenance doth behold the upright.
