Deuteronomy 29:15 - Matthew Poole's English Annotations on the Holy Bible

i.e. With your posterity; for so the covenant was made at first with Abraham and his seed, by which, as God engaged himself to continue the blessing of Abraham upon his posterity, so he also engaged them to the same duties and conditions which were required of Abraham. So it is even among men, where a king confers an estate upon a subject and his heirs for ever, upon some certain conditions, all his heirs who enjoy that benefit are obliged to the same conditions. But whatsoever becomes of man's right, God the Creator and sovereign Lord of all men and things hath an unquestionable right and power to oblige all persons that are or shall be to such conditions as he pleaseth, and especially to such conditions as are for their own benefit, which is the present case.
