Jacob, after all this, reverts to his old habits and tricks. God changes Esau from a wild, revengeful man into a kindly one. Sometimes we greatly fear a situation and we are not doing what Philippians 4:6 tells us.
V.17-20 You will notice the four things Jacob builds when he gets back to his land. First, a house (not an altar as in Gen. 26:25). Secondly, booths (stables) for his cattle. As he moves on into the land, he has other thoughts. Thirdly, he bought a field. And lastly, he builds an altar — God last! See Genesis 26:25 comments on the meaning of these things.
