Please generate an artful and respectful scene from the biblical tale of Exodus 14:7. Depict this scene in the style of pointillism, a popular art style used before 1912, characterized by the use of small, distinct dots of pure color. The scene involves six hundred chosen chariots, each driven by a captain. Each chariot should be ornately decorated as befits ancient Egyptian royalty, and the captains should exude authority and reverence. Background should feature the expanses of ancient Egypt, full of sand dunes and pyramids. Please ensure the artwork does not contain any text or words and resonates with a devotional aura, as per Christian beliefs.
