Matthew Poole and continuators on Genesis 23:9

9 That he may give me the cave of Machpelah , which he hath, which is in the end of his field: for as much money as it is worth , he shall give it me, for a possession of a burying-place amongst you.

Which seems to be the proper name of the place, ver. 17, 19. so called from its duplicity, because the cave was double, either one for Men, and another for Women: Or the one served onely for an entrance into the other, which was the burying place.

Heb. For full money, 1 Chron. 21. 22, 24. i. e. for money of full weight answerable to its worth.

Marginal references: Or, double cave.; Heb. full money.
