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.
30 Even youths grow tired and weary, and young men stumble and fall; 31 but those who hope in the LORDwill renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
22 “Yet you have not called on me, Jacob, you have not wearied yourselves for me, Israel. 23 You have not brought me sheep for burnt offerings, nor honored me with your sacrifices. I have not burdened you with grain offerings nor wearied you with demands for incense. 24 You have not bought any fragrant calamus for me, or lavished on me the fat of your sacrifices. But you have burdened me with your sins and wearied me with your offenses.
12 “Keep on, then, with your magic spells and with your many sorceries, which you have labored at since childhood. Perhaps you will succeed, perhaps you will cause terror.
15 That is all they are to you— these you have dealt with and labored with since childhood. All of them go on in their error; there is not one that can save you.
4 But I said, “I have labored in vain; I have spent my strength for nothing at all. Yet what is due me is in the LORD’s hand, and my reward is with my God.”
10 You wearied yourself by such going about, but you would not say, ‘It is hopeless.’ You found renewal of your strength, and so you did not faint.
8 The LORD has sworn by his right hand and by his mighty arm: “Never again will I give your grain as food for your enemies, and never again will foreigners drink the new wine for which you have toiled;
23 They will not labor in vain, nor will they bear children doomed to misfortune; for they will be a people blessed by the LORD, they and their descendants with them.
