Amos 8:4-6

“Hear this, you who swallow up the needy, and cause the poor of the land to fail, saying, ‘When will the new moon be gone, that we may sell grain? And the Sabbath, that we may offer wheat for sale? Making the ephah small and the shekel large, and dealing falsely with balances, that we may buy the poor for silver, and the needy for a pair of sandals, and sell the refuse of the wheat.’”

The prophet Amos, a shepherd and fig-picker from Judah, delivered messages of judgment against the northern kingdom of Israel in the 8th century BCE. He spoke at a time of apparent prosperity, but also profound social decay, highlighting the disconnect between religious practice and ethical living.

What practices today, veiled by custom or economic systems, might similarly exploit the vulnerable for profit?

Then — the setting

Amos prophesied to the northern kingdom of Israel around 760-750 BCE, during the reign of Jeroboam II. This was a period of relative peace and economic prosperity, especially for the elite, following a period of Assyrian weakness. However, this prosperity was built on and exacerbated deep social inequalities. The injustices Amos confronted were primarily economic and judicial: merchants were rigging scales (making the 'ephah small' for buying, and the 'shekel large' for selling, and using 'false balances') to cheat customers, especially the poor. They were exploiting their workers and debtors, even selling people into slavery for trivial debts ('a pair of sandals'). They also showed impatience with religious observances like the New Moon festival and the Sabbath, because these interrupted their profit-making. These practices directly violated the covenantal laws of Israel, which commanded fair weights and measures, and protection for the poor and vulnerable.

Across the Testaments

In the Old Testament, Amos stands among a chorus of prophets (like Isaiah, Micah, Jeremiah) who consistently highlight God's concern for justice and the poor, often linking true worship with ethical conduct. They challenge the idea that ritual observance alone is sufficient if justice is neglected. The New Testament carries this theme forward, with Jesus frequently condemning the abuse of power and wealth (e.g., in his parables about the rich fool or the rich man and Lazarus, or his cleansing of the temple where merchants exploited worshippers). The early Christian community, as depicted in Acts, sought to address economic disparities by sharing resources, echoing the prophetic call for equitable community life rather than exploitation.
