This section shows how people were ranked socially in ancient Near Eastern cultures. An adult working man had the highest rank, followed by an adult working woman. A boy ranked higher than a girl, and both ranked higher than toddlers. Senior citizens, who were past their prime working age, ranked similarly to boys and girls.
The amount of fifty shekels was about 570 grams (20 ounces) of silver, which was a lot (see study note on Leviticus 5:15). Comparisons with other writings from that time show that the biblical shekel value was very high and unaffordable for most people.
