If thou shalt hearken unto the voice of the Lord thy God,.... Or rather, "for thou shalt hearken" (p); seeing it is before promised that the Lord would circumcise their hearts to love him, and they should obey his voice, Deu 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, Deu 30:8. (p) "quia obedies", Cocceius.
