Isaiah 40:29 (KJV)

What does Isaiah 40:29 mean?

Isaiah 40:29 says that God gives power to those who are exhausted and increases strength for people who have none left. The verse highlights that when people reach the end of their own resources, God is the one who supplies what they lack.

The prophet Isaiah is speaking to the people of Israel, who are weary and discouraged, likely during or after a time of hardship and exile. Isaiah reassures them that God is not limited by human weakness; instead, God is able and willing to renew those who feel powerless or worn out.

The Hebrew behind Isaiah 40:29

• "Power" (כֹּחַ, koach, H3581) refers to physical or inner strength, the ability to keep going. The verse stresses that this strength comes from God, not from within ourselves.
• "Faint" (יָעֵף, ya'ef, H3287) describes someone who is weary to the point of collapse. Isaiah uses this word to show the depth of human exhaustion addressed here.
• "Might" (אוֹן, on, H202) means vigor or capacity. The verse singles out those who have absolutely no might left, emphasizing complete emptiness.
• "Increaseth" (יַרְבֶּה, yarbeh, H7235) means to make something greater or multiply it. God doesn’t just restore a little strength—He multiplies it for those who need it most.
• "Strength" (עָצוּם, atzum, H6109) can mean powerful or mighty. Here, it highlights the kind of strength God provides, which is substantial and effective.

Why Isaiah 40:29 matters

• Isaiah 40:29 corrects the idea that God only helps those who are already strong or capable; instead, God’s help is especially for the completely worn out.
• The verse connects to the wider chapter, which contrasts human frailty with God’s endless power and care, offering hope to people who feel forgotten or overwhelmed.
• This verse clarifies that God’s strength is not just a small boost but a real and abundant supply for those who have nothing left to give.
