What biblical figure advocated for the poor and marginalized in Israel?

The figure who notably advocated for the poor and marginalized in Israel is Amos. He was a prophet during the 8th century BC, a time when the northern kingdom of Israel was experiencing prosperity but also significant social injustice. Amos's writings emphasize the need for justice and righteousness, condemning the wealthy elite for their exploitation of the poor. He famously proclaimed that God despised the empty rituals and sacrifices of the people, pointing out that true worship should be accompanied by social justice and concern for the oppressed. His famous declaration to "let justice roll down like waters" reflects his commitment to the plight of the marginalized and highlights God's demand for equity in society. Amos's prophetic ministry serves as a critical voice calling for accountability among the powerful on behalf of those who are suffering.
