If thou shalt hearken unto the voice of the Lord thy God,.... Or rather, "for thou shalt hearken" ; seeing it is before promised that the Lord would circumcise their hearts to love him, and they should obey his voice, De 30:6.
The Targum is,"receive the Word of the Lord:''to keep his commandments and his statutes, which are written in this book of the law; particularly in this chapter, and all that are of a moral nature:[and] if thou return unto the Lord thy God with all thy heart, and with all thy soul; or, "for thou shall return", &c.
as it is promised they should, De 30:8.
