The concept of weighing the heart (21:2) originated in Egypt. Egyptians believed that when a person died, the gods placed that person’s heart on a set of golden scales along with the Feather of Truth. If the heart weighed less than the feather, the person was admitted into the afterlife. It is possible that the Israelites brought this imagery with them when they left Egypt and replaced the Egyptian gods with Yahweh, who is the true judge of the heart.
