Isaiah 49:28-31
28 Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.
29 He giveth power to the faint; and to them that have no might he increaseth strength.
30 Even the youths shall faint and be weary, and the young men shall utterly fall:
31 But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
Psalm 130
130 Out of the depths have I cried unto thee, O Lord.
2 Lord, hear my voice: let thine ears be attentive to the voice of my supplications.
3 If thou, Lord, shouldest mark iniquities, O Lord, who shall stand?
4 But there is forgiveness with thee, that thou mayest be feared.
5 I wait for the Lord, my soul doth wait, and in his word do I hope.
6 My soul waiteth for the Lord more than they that watch for the morning: I say, more than they that watch for the morning.
7 Let Israel hope in the Lord: for with the Lord there is mercy, and with him is plenteous redemption.
8 And he shall redeem Israel from all his iniquities.
Psalm 27
27 The Lord is my light and my salvation; whom shall I fear? the Lord is the strength of my life; of whom shall I be afraid?
2 When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.
3 Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
4 One thing have I desired of the Lord, that will I seek after; that I may dwell in the house of the Lordall the days of my life, to behold the beauty of the Lord, and to enquire in his temple.
5 For in the time of trouble he shall hide me in his pavilion: in the secret of his tabernacle shall he hide me; he shall set me up upon a rock.
6 And now shall mine head be lifted up above mine enemies round about me: therefore will I offer in his tabernacle sacrifices of joy; I will sing, yea, I will sing praises unto the Lord.
7 Hear, O Lord, when I cry with my voice: have mercy also upon me, and answer me.
8 When thou saidst, Seek ye my face; my heart said unto thee, Thy face, Lord, will I seek.
9 Hide 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.
10 When my father and my mother forsake me, then the Lord will take me up.
11 Teach me thy way, O Lord, and lead me in a plain path, because of mine enemies.
12 Deliver me not over unto the will of mine enemies: for false witnesses are risen up against me, and such as breathe out cruelty.
13 I had fainted, unless I had believed to see the goodness of the Lord in the land of the living.
14 Wait on the Lord: be of good courage, and he shall strengthen thine heart: wait, I say, on the Lord.
