He gives power to the faint, and to him who has no might he increases strength. Even youths shall faint and be weary, and young men shall fall exhausted; but they who wait for the LORD shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.

he increases strength
Koach · koach · H3581 · HEBREW
strength, power, might — the capacity to act when one is spent
The word koach appears 125 times in the Hebrew Old Testament, and it almost always refers to a force that can be depleted. Caregivers know this depletion. You give and give — lifting, watching, praying, staying — and there comes a moment when your own koach is gone. Isaiah 40:29 describes the God who gives koach to the faint: not a God who tells you to find more strength inside yourself, but one who transfers his own endless supply to the one who has run out.
1 Kings 19 · The Angel and the Sleeping Prophetthey who wait for the LORD
Qavah · qavah · H6960 · HEBREW
to wait, to hope, to bind together — like cords being twisted into rope
The root of qavah carries the image of cords being wound and twisted together to form rope. Waiting on God, in the Hebrew imagination, is not passive — it is the act of binding your life to his, of weaving your strength into his, until you cannot tell where you end and he begins. Caregivers are often told to "take care of themselves," and that counsel is not wrong. But Isaiah 40:31 goes deeper: the source of renewed strength is not self-care but God-binding. Those who wait for the LORD — who stay attached to him in the long middle — find their strength renewed.
Acts 1–2 · Ten Days in the Upper Roomwings like eagles
Nešer · nešer · H5404 · HEBREW
eagle — the bird that soars on updrafts without beating its wings
The nešer — eagle — does not power its way through the sky. It finds thermal updrafts, spreads its massive wings, and rises on the wind that someone else provides. Isaiah 40:31 promises not the strength to flap harder, but the ability to soar differently. Caregivers often try to manage their exhaustion through willpower, better schedules, and forcing themselves to keep going. The nešer image suggests something else: what if the answer is not more effort but a different kind of lift?

Prayer
Father, I come to you as the one beside the bed — the one who has been giving and watching and praying and staying. I don't always know what to ask for. I know I am tired. I know the journey is too great for me alone. But that is exactly where you meet people, and I am choosing to believe you meet me here too. Give me koach — strength that is not my own, poured into the places where mine has run out. Teach me qavah — how to bind myself to you in the long middle, when nothing has resolved and I am still here. Lift me on the nešer wings — not out of this, but through it, and into a deeper knowing of who you are. Where I feel guilty for not being enough, remind me that I am not supposed to be enough. Where I feel invisible, remind me that you see every quiet act of love. Where I feel forgotten, remind me that you bore your own people on eagles' wings when they could not escape on their own. Renew me — outer and inner. Fill me before you send me back. And let the one I am caring for see something of you in the way I show up. In Jesus' name, Amen.
