what modern economic practices might unintentionally delay payment or disadvantage vulnerable workers?

Adds the setting and its conversation across both testaments.

Deuteronomy 24:14-15

““You shall not oppress a hired servant who is poor and needy, whether he be of your brothers, or of your foreigners who are in your land within your gates. In his day you shall give him his wages, neither shall the sun go down on it; for he is poor, and sets his heart on it, lest he cry against you to Yahweh, and it be sin to you.””

Deuteronomy is a book attributed to Moses, presented as his final address to the Israelites before they enter the promised land. It reiterates and expands upon the laws given at Sinai, preparing the new generation for life in Canaan. This section specifically deals with social justice and ethical conduct within the community.

what responsibility might employers have to understand the full impact of their payment systems on their most vulnerable workers?

Then — the setting

This passage, likely written or compiled around the 7th-5th centuries BCE, reflects an agrarian society where daily laborers, often poor, depended on immediate payment for their sustenance. Without banks or credit systems, a day's wages were necessary to buy food for that day and to prevent destitution. The injunction 'neither shall the sun go down on it' underscores the critical need for prompt payment, framing delayed wages as a form of oppression.

Across the Testaments

In the Old Testament, particularly the Torah and Prophets, timely payment and fair treatment of the poor and vulnerable are recurring themes, rooted in God's character as a deliverer of the oppressed. This Deuteronomic law provides a foundational ethical standard. The New Testament affirms and intensifies this concern; for example, James 5:4 directly condemns those who withhold wages from workers, declaring that the cries of the laborers have reached the ears of the Lord. The New Testament often broadens the scope of justice to include attitudes and intentions, not just actions, and connects it to the coming kingdom of God, but the core principle of protecting vulnerable workers through fair and timely remuneration remains consistent.
