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 63 — A Psalm of David, when he was in the wilderness of Judah.
O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is;
To see thy power and thy glory, so as I have seen thee in the sanctuary.
Because thy lovingkindness is better than life, my lips shall praise thee.
Thus will I bless thee while I live: I will lift up my hands in thy name.
My soul shall be satisfied as with marrow and fatness; and my mouth shall praise thee with joyful lips:
When I remember thee upon my bed, and meditate on thee in the night watches.
Because thou hast been my help, therefore in the shadow of thy wings will I rejoice.
My soul followeth hard after thee: thy right hand upholdeth me.
But those that seek my soul, to destroy it, shall go into the lower parts of the earth.
They shall fall by the sword: they shall be a portion for foxes.
But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped.
