King James Version (KJV)
Hast thou not known? hast thou not heard, {that} the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? {there is} no searching of his understanding.
Modern English
Haven’t you known? Haven’t you heard? The everlasting God, Yahweh, The Creator of the ends of the earth, doesn’t faint. He isn’t weary. His understanding is unsearchable.
