Isaiah 40:31 (KJV)

What does Isaiah 40:31 mean?

Isaiah 40:31 promises that those who patiently trust and rely on the LORD will find their strength renewed, allowing them to rise up like eagles, run without growing tired, and walk without becoming faint. The verse uses vivid images to show that God gives endurance and energy to those who look to Him, even when they feel worn out.

Isaiah is speaking to the people of Israel, who were discouraged and weary, likely during a time of exile or hardship. The verse reassures them that waiting on the LORD—meaning to hope in Him and trust His timing—brings a deep, ongoing renewal that goes beyond physical strength. The language paints a picture of God’s power lifting people above their troubles, giving them the ability to keep going when they would otherwise give up.

The Hebrew behind Isaiah 40:31

• "wait" (קָוָה, qavah): This word means more than just passing time; it carries the sense of hoping, expecting, and looking to God with trust. It is an active, hopeful waiting, not passive.
• "renew" (חָלַף, chalaph): This word means to change or exchange, suggesting that God gives a fresh supply of strength, not just a recharge of old energy.
• "strength" (כֹּחַ, koach): This word refers to ability, power, or might, highlighting that the renewal is real and practical, not just a feeling.
• "mount up" (עָלָה, alah): This word means to go up or ascend, and here it creates the image of soaring high above difficulties, like an eagle rising on the wind.

• The verse emphasizes that God’s renewal is not just spiritual encouragement but a real, practical strengthening for life’s challenges.
• In the wider context of Isaiah 40, this verse is a turning point from despair to hope, assuring God’s people that He has not forgotten them and will provide what they need to endure.
