The field of Ephron, which was in Machpelah - which was before Mamre - was made over. . . Verse 17.

In addition to this,

After this, Abraham buried Sarah his wife at the cave of the field of Machpelah facing Mamre. Verse 19.

And yet again,

The field and the cave which was in it were made over to Abraham as a possession for a grave, from the sons of Heth. Verse 20.

Also in Genesis 25,

They buried Abraham at the cave of Machpelah, at the field of Ephron the son of Zohar the Hittite, which faced Mamre. The field which Abraham bought from the sons of Heth . . . Verses 9, 10.

In Genesis 49,

Bury me in the cave which is in the field of Machpelah, which faces Mamre, in the land of Canaan, which Abraham bought with the field from Ephron the Hittite as a possession for a grave. The buying of the field and the cave that was in it was from the sons of Heth. Verses 30-32.

And in the present chapter,

They buried him in the cave of the field of Machpelah, which Abraham had bought with the field, as a possession for a grave, from Ephron the Hittite - facing Mamre. Something special is meant by this frequent repetition involving practically the same words, for the following reason: 'Abraham', 'Isaac', and 'Jacob' represent the Lord; 'the burial of them' represents resurrection and restoration to life, 'the field of the cave of Machpelah' the beginning of regeneration, 'Ephron the Hittite' those who receive the good of faith and allow themselves to be regenerated, and 'the sons of Heth' a spiritual Church. Thus because these words in a brief way mean the establishment of a spiritual Church, the same details are repeated so many times.
