I find it unsettling that four of Israel’s major enemies are “family.” Now at times, they were civil towards one another and we have to remember that Ruth, David’s and Jesus’ grandmother, was a Moabitess. But Edom, Moab, and Ammon are frequently mentioned together as joining forces to fight Israel and in many of the Prophetic Books, they are together when the Lord is handing out judgment.
It should also be noted that God warns Moses and the Israelites about fighting with them on the way back to the Promised Land. In Deuteronomy 2:5,9,19 it is stated that each of them had been given that land by the Lord and Israel was not to start trouble.
Lot is the father of Moab and Ammon (see Timeline) by his daughters after the destruction of Sodom and Gomorrah (Genesis 19:30 – 38). Now a question that has been asked is whether they should have ever been there, to begin with! Abraham was to leave his country and family and go to the Promised Land but there is Lot with his uncle as he leaves the rest of the family.
