Nimrod built his city by slavery, and the relationship between the polis and slavery is an inescapable symbiosis. The Biblical alternative to slavery to the State is domestic (household) apprenticeship.
1. Genesis 10:8; 9:25-27; 47:21 (LXX [NIV])
2. Proverbs 17:2 + Genesis 15:2-3; 17:12; 14:14; Exodus 21:2-11; Deuteronomy 15:12-18; Jeremiah 34:8-17; Leviticus 25:39ff.
Nimrod: The "Hunter" Of Men
The commentators are fairly agreed that Nimrod was a violent enslaver of men. Slavery, however, is inescapable, at least in non-Christian cultures. Abraham is the Christian anti-type of Nimrod, building his household by evangelism and domestic apprenticeship. Secular Humanists would say Abraham's "servants" should have been "emancipated" -- that homeless autonomy is better than working in a Christian household.
