Final answer:
The Exodus is the event that opens the door for a more general form of natural law in the Old Testament, as it is when the Hebrews agree to worship Yahweh exclusively and follow the Ten Commandments.
Step-by-step explanation:
The door for a more general form of natural law in the Old Testament opens with the Exodus. During the mass migration of Hebrews out of Egypt under the leadership of Moses, they entered into an agreement to exclusively worship Yahweh and adhere to his laws, which notably included the Ten Commandments. This covenant was crucial in establishing a broader framework of natural law that was intended to guide the Hebrew people in moral behavior and social governance. It placed a divine authority on these laws, suggesting that they were inherently bound to the natural order created by God.
