'Enslaved' in the Bible

Then the Lord said to Abram, “Know this for certain: Your offspring will be foreigners in a land that does not belong to them; they will be enslaved and oppressed 400 years.

We and our children are just like our countrymen and their children, yet we are subjecting our sons and daughters to slavery. Some of our daughters are already enslaved, but we are powerless because our fields and vineyards belong to others.”
