and a curse, if you do not obey the commands of the Lord your God, and you turn aside from the path I command you today by following other gods you have not known.
When the Lord your God brings you into the land you are entering to possess, you are to proclaim the blessing at Mount Gerizim and the curse at Mount Ebal.

be careful to follow all the statutes and ordinances I set before you today.
