Psalm 27:10

⁷Hear, O Lord, when I cry with my voice: have mercy also upon me, and answer me. ⁸When thou saidst, Seek ye my face; my heart said unto thee, Thy face, Lord, will I seek. ⁹Hide not thy face far from me; put not thy servant away in anger: thou hast been my help; leave me not, neither forsake me, O God of my salvation. ¹⁰When my father and my mother forsake me, then the Lord will take me up. ¹¹Teach me thy way, O Lord, and lead me in a plain path, because of mine enemies. ¹²Deliver me not over unto the will of mine enemies: for false witnesses are risen up against me, and such as breathe out cruelty. ¹³I had fainted, unless I had believed to see the goodness of the Lord in the land of the living.
