Amos 2:6

Israel’s first sin was that the Israelites took advantage of righteous, needy people for their own personal, material advantage and sold them into slavery, perhaps into debt (cf. 2 Kings 4:1-7). They sold, for the price of what they owed, honest people who would have repaid their debts if given the opportunity. They would even sell into slavery someone who could not pay the small price of a pair of sandals. Another interpretation is that they would take as a bribe as little as what a pair of sandals cost. The Israelites should have been generous and openhanded toward the poor (Deuteronomy 15:7-11). Sin often results in the devaluation of human life.
