First, Esau didn't marry godly women like Jacob waited to do. They ended up leading his family away from the Lord. It says in 2 Corinthians, "Do not be unequally yoked with an unbeliever." It doesn't seem as big of a deal to date someone that is not a Christian, but we marry the people we date. And a good and healthy marriage is impossible without the center point of Christ.
There are so many points in life that I so do not want to hold my tongue, that I don't want to put my husband first, that I don't want to clean the house, that I don't want to wait until my husband and I can see the movie together --- the moments that my desires are selfish instead of selfless, that's when I have to turn to Jesus. And I know my husband has the same thing. Without God, I can guarantee our marriage would be much angrier, much unhappier and much less solid.
Esau also wasn't careful about where his family lived. He took his family outside of the Promised Land. It's important where we live. It's important the environment our children are in. Can I relate this to the black lives matter movement? The biggest point against what this movement seems to stand for is that the biggest violence against blacks is blacks, but they don't seem to make a big deal of this. "That's just the culture where we live. We have to deal with it. That's the only place we can afford." I bet that's true in big cities, but take your family to a small town and you will be amazed at what you can afford. Esau thought he had to leave the Promised Land to have enough room for all his stuff, but had he prioritized his family he would have chosen where to live on different parameters. We should all pick where we live based on what is best for our families.
Esau's family does become a ruling family where it settled down. His sons and grandsons became chiefs, which means rulers over 1,000 plus. One of Esau's wives was Oholibamah, who was a part of a ruling family, so many of the men in their family also became rulers. That looks good, but Esau was becoming assimilated into an ungodly culture. He was no different than anyone else.
The judgment on the Edomites, Esau's family, has lasted generation after generation. From Old Testament times to today in the Middle East, God's judgement has been on that land. We never think that what we do will affect our families for that long, but it can. From who we marry to where we live, it's these decisions that make up a life, a family and a future. Make wise choices.
