For if ye shall diligently keep all these commandments which I command you to do them,.... Observe and take notice of them, even all of them, and so as not merely to have a theory or notional knowledge of them, but to put them in practice: to love the Lord your God; and show it by obeying his commands, and which is the end of the commandment, and the principle from which all obedience should flow: to walk in all his ways, and to cleave unto him; see Deu 10:12.
