Be strong, and let your heart take courage, all ye that hope in Jehovah.
If thou losest courage in the day of trouble, thy strength is small.
Dost thou not know, hast thou not heard, that the everlasting God Jehovah, the Creator of the ends of the earth, fainteth not nor tireth? There is no searching of his understanding.
He giveth power to the faint; and to him that hath no might he increaseth strength.
Even the youths shall faint and shall tire, and the young men shall stumble and fall;
but they that wait upon Jehovah shall renew their strength: they shall mount up with wings as eagles; they shall run, and not tire; they shall walk, and not faint.
And he said to me, My grace suffices thee; for my power is perfected in weakness. Most gladly therefore will I rather boast in my weaknesses, that the power of the Christ may dwell upon me.
Wherefore I take pleasure in weaknesses, in insults, in necessities, in persecutions, in straits, for Christ: for when I am weak, then I am powerful.
I have strength for all things in him that gives me power.
