Deuteronomy 28:15  (King James Version)
But it shall come to pass, if thou wilt not hearken unto the voice of the LORD thy God, to observe to do all his commandments and his statutes which I command thee this day; that all these curses shall come upon thee, and overtake thee:

if thou wilt
Leviticus 26:14-46 ; Lamentations 2:17 ; Daniel 9:11-13 ; Malachi 2:2 ; Romans 2:8 Romans 2:9

all these curses
The same variety of expression is used in these terrible curses, as in the preceding blessings, to intimate every kind of prosperity or adversity, personal, relative, and public. Consulting the marginal references will generally lead to the best exposition of the terms employed; and will frequently point out the fulfilment of the promises and threatenings.
