Isaiah 40
25 "To whom will you compare me? Or who is my equal?" says the Holy One. 26 Lift your eyes and look to the heavens: Who created all these? He who brings out the starry host one by one, and calls them each by name. Because of his great power and mighty strength, not one of them is missing.
27 Why do you say, O Jacob, and complain, O Israel, "My way is hidden from the Lord; my cause is disregarded by my God"? 28 Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. 29 He gives strength to the weary and increases the power of the weak. 30 Even youths grow tired and weary, and young men stumble and fall; 31 but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
Isaiah 50:4-9
4 The Sovereign Lord has given me an instructed tongue, to know the word that sustains the weary. He wakens me morning by morning, wakens my ear to listen like one being taught. 5 The Sovereign Lord has opened my ears, and I have not been rebellious; I have not drawn back. 6 I offered my back to those who beat me, my cheeks to those who pulled out my beard; I did not hide my face from mocking and spitting. 7 Because the Sovereign Lord helps me, I will not be disgraced. Therefore have I set my face like flint, and I know I will not be put to shame. 8 He who vindicates me is near. Who then will bring charges against me? Let us face each other! Who is my accuser? Let him confront me! 9 It is the Sovereign Lord who helps me. Who is he that will condemn me? They will all wear out like a garment; the moths will eat them up.
Matthew 11:28
28 "Come to me, all you who are weary and burdened, and I will give you rest.
Jeremiah 31
5 I will refresh the weary and satisfy the faint.
