What does Genesis 23:16 mean?
Abraham's negotiation with Ephron the Hittite for the purchase of his cave and field at Machpelah has concluded. Negotiation may not be quite the right word, however. Abraham immediately accepts the first price Ephron mentions, agreeing to purchase the field along with the cave he initially asked about.For Abraham, the most important thing was to have the full legal ownership rights to this property, something he ensured by purchasing the cave and field in full view of the "people of the land" (Genesis 23:12). There could be no legitimate dispute as to who owned this property.
Why was this so important? In this era, people were often buried in their homeland, entombed along with their ancestors. Abraham's decision to bury Sarah, and later to be buried himself, in Canaan, was a declaration of faith that this would become the permanent homeland of his offspring. This is somewhat unusual, also, in that the land Abraham has just purchased is part of what God has promised to his descendants.
