Isaiah 51:15 (KJV)

What does Isaiah 51:15 mean?

Isaiah 51:15 describes God as the one who has power over the sea, able to divide it and calm its roaring waves, and declares that his name is "the LORD of hosts." This verse emphasizes God's authority and might, reminding the people of Israel of his past acts and his identity as their powerful protector.

In this verse, the prophet Isaiah is speaking to the people of Israel, who are facing hardship and uncertainty. Isaiah points them back to God's past deliverance—especially the parting of the sea during the Exodus—to reassure them that the same God who controlled the sea is still with them. The title "the LORD of hosts" highlights God's command over all heavenly and earthly forces.

The Hebrew behind Isaiah 51:15

• LORD (יְהוָה, Yahweh): This is the personal name of God, often translated as "the LORD" in English Bibles, emphasizing God's unique identity and covenant relationship with Israel.
• divided (רָגַע, raga‘): This word means to still, calm, or divide, and here it refers to God's act of parting the sea, recalling the Exodus event and God's power to bring order out of chaos.
• sea (יָם, yam): The sea often represents chaos or danger in Hebrew thought, so God's control over it is a sign of his supreme authority.
• hosts (צָבָא, tsava’): This term means "armies" or "forces," and when used in the title "the LORD of hosts," it points to God's rule over all spiritual and earthly powers.
