'Severity' in the Bible
So Joseph bought all the land of Egypt for Pharaoh; for every Egyptian sold his field because the famine was severe upon them. So the land became Pharaoh’s.
They made their lives bitter with hard labor in mortar, brick, and all kinds of field work. All their labor was harsh and severe.
You shall not rule over him with harshness (severity, oppression), but you are to fear your God [with profound reverence].
You may even bequeath them as an inheritance to your children after you, to receive as a possession; you can use them as permanent slaves. But in respect to your fellow countrymen, the children of Israel, you shall not rule over one another with harshness (severity, oppression).
Like a man hired year by year he shall deal with him; he shall not rule over him with harshness in your sight.
