Deuteronomy 11:28 Meaning and Commentary

Deuteronomy 11:28

And a curse, if ye will not obey the commandments of the Lord
your God
Accursed in body and estate, in basket and store; in their families, flocks, and herds; within doors and without; in city, and country; going out, or coming in; in this world, and that to come, if divine goodness prevent not; see ( Deuteronomy 28:15-20 ) ( 29:20 )

but turn aside out of the way which I command you this day;
which the law he gave them, and repeated to them, directed them to walk in:

to go after other gods, which ye have not known;
to serve and worship the gods of other nations, strange gods, which neither they nor their fathers knew anything of, or ever received any good thing from; and which indeed are no gods, and nothing in the world, as an idol is.
