The quote "The first duty of government is to protect the powerless from the powerful" from the Code of Hammurabi highlights the government's role in ensuring justice and protecting those who are vulnerable or marginalized in society. Therefore, the most accurate interpretation of its importance would be:
Solidified that the government created laws in order to protect the commoner.
This reflects the intention behind establishing laws to maintain order and safeguard the rights and well-being of individuals, particularly those without power.
