What does the Bible say about strength when you are weary?

“He gives power to the weak. He increases the strength of him who has no might. Even the youths faint and get weary, and the young men utterly fall; but those who wait for the LORD will renew their strength. They will mount up with wings like eagles. They will run, and not be weary. They will walk, and not faint.”

““Come to me, all you who labor and are heavily burdened, and I will give you rest.”

“He has said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me.”

“Let’s not be weary in doing good, for we will reap in due season if we don’t give up.”

“I can do all things through Christ who strengthens me.”

“God is our refuge and strength, a very present help in trouble.”

“Then he said to them, “Go your way. Eat the fat, drink the sweet, and send portions to him for whom nothing is prepared, for today is holy to our Lord. Don’t be grieved, for the joy of the LORD is your strength.””

“Don’t you be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness.”
