Moses frames his non-negotiable demand as a rhetorical question to emphasize Israel’s absolute need for their livestock in worship. By asking rather than declaring, he invites Pharaoh to acknowledge the reasonableness of the requirement while simultaneously asserting that compromise is impossible. The question format softens the confrontation while maintaining firmness.

Pharaoh became enraged at Moses’s demand and refused permission for the livestock to accompany Israel. He expelled Moses from his presence and threatened him with death if he returned (Exodus 10:28).

Moses’s question functions as an ultimatum disguised as explanation. He argues from two grounds: theological necessity and practical ignorance. The phrase ‘not a hoof’ (Hebrew ‘parsah’) intensifies the requirement through extreme language, meaning absolutely every animal must accompany them. Moses questions rather than states to force Pharaoh to confront the logic—how can Israel worship Yahweh without the means to sacrifice? The second half reveals strategic wisdom: ‘we know not with what we must serve the LORD until we come thither.’ Moses refuses to specify exact requirements, preventing Pharaoh from calculating and limiting what they take. This question carries weight because it exposes the fundamental incompatibility between Egyptian control and Israelite worship.
