What does Genesis 33:5 mean?
Prior verses broke twenty years' worth of tension, between brothers split by betrayal and threats of violence (Genesis 27:41–45). Jacob was so concerned about this meeting that he'd split his caravan (Genesis 32:7–8), flattered Esau with gifts (Genesis 32:13–15), and even arranged his immediate family to enable escape (Genesis 33:1–3). After all that, Esau turns out to be happy to see his brother, running into his arms and weeping (Genesis 33:4).Now, Esau looks up and notices Jacob's wives and children approaching in several groups. He asks who they are. Jacob tells his brother these are the children God has graciously given to "your servant." This insistent use of humility might be Jacob's way of expressing apology for his past behavior (Genesis 27:19). Or, it might be simple politics and cultural custom.
Esau would most likely be impressed by what he sees. Jacob left home with nothing—sleeping alone on rocks (Genesis 28:10–11). To return twenty years later with immense wealth, and 11 sons, would be seen as a significant achievement.
