And the Egyptians shall know that I am the LORD is identical with the same phrase in verse 4. When I have gotten glory is literally “in my being honored.” Over Pharaoh, his chariots, and his horsemen repeats what is in verse 17, except for “all his host.” In some languages this repetition will sound unnatural, but in Hebrew it adds to the impact of the story. Good News Translation summarizes all these words rather than repeat them: “When I defeat them.”
