Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?

Isaiah 51:9 (KJV)

What does Isaiah 51:9 mean?

Isaiah 51:9 is a prayer calling on God’s power to act again as in the past, asking the “arm of the LORD” to awaken and show strength like in ancient times when God defeated great enemies. The verse remembers God’s past victories, mentioning the cutting of “Rahab” and the wounding of “the dragon,” as symbols of chaos or powerful foes.

In this verse, the prophet Isaiah is speaking to God on behalf of the people of Israel, who are feeling discouraged and longing for deliverance. Isaiah uses poetic language to remind God—and the people—of the mighty acts God performed long ago, encouraging faith that God can save them again. The mention of “Rahab” and “the dragon” points to legendary enemies or forces of chaos that God overcame, reinforcing the hope that God’s power has not changed.

The Hebrew behind Isaiah 51:9

  • “Awake” (עוּרִי, ‘uri): This word is repeated three times, emphasizing urgency and a desperate plea for God to take action, as if God’s power has been dormant.
  • “Arm” (זְרוֹעַ, zeroa‘): In Hebrew thought, the “arm” of the LORD is a symbol for God’s strength and ability to save, not a literal body part.
  • “Rahab” (רַהַב, Rahav): Here, “Rahab” is not the woman from Jericho but a poetic name for a mythical sea monster or a symbol of Egypt, representing chaos or a powerful enemy God defeated.
  • “Dragon” (תַּנִּין, tannin): This word refers to a great sea creature or dragon, another symbol of chaos or evil that God conquered in ancient stories.

Why Isaiah 51:9 matters

  • Isaiah 51:9 helps clear up that “Rahab” in this verse is a symbol for a chaotic force or Egypt, not a person, which can be confusing since the same name appears elsewhere in the Bible.
  • The verse emphasizes that God’s power is not just a thing of the past; it invites readers to trust that God can still act with the same strength today.
  • This verse connects to the wider passage by setting up a theme of remembering God’s faithfulness in history as a reason for hope in the present struggles of the people.
