Take good heed - unto yourselves that ye love the Lord - לנפשתיכם lenaphshotheychem, Take heed To Your Souls, literally; but נפש nephesh and nefs, both in Hebrew and Arabic, signify the whole self, as well as soul and life; both soul and body must be joined in this work, for it is written, Thou shalt love the Lord thy God with all thy heart, soul, mind, and strength.

Take good heed therefore unto yourselves,.... To be upon their guard, and to be watchful, were very necessary to them, that they might not be ensnared by the Canaanites, and drawn aside by them into idolatry, and so apostatize from the Lord and his worship, since their temptations would be many:

that ye love the Lord your God; which would the most strongly influence and engage them to serve and worship the Lord, and obey his commands, and be the best preservative against idolatry and false worship.

Take good heed, therefore, that ye love the Lord your God--The sum of his exhortation is comprised in the love of God, which is the end or fulfilment of the law (Deu 6:5; Deu 6:11:13; Mat 22:37).
