Go, set a watchman, let him declare what he seeth—God's direction to Isaiah to set a watchman to "declare" what he sees. But as in Isaiah 21:10, Isaiah himself is represented as the one who "declared." HORSLEY makes him the "watchman," and translates, "Come, let him who standeth on the watchtower report what he seeth."
