John Gill Commentary Deuteronomy 10:12

"And now, Israel, what doth Jehovah thy God require of thee, but to fear Jehovah thy God, to walk in all his ways, and to love him, and to serve Jehovah thy God with all thy heart and with all thy soul," — Deuteronomy 10:12 (ASV)

And now, Israel, what does the Lord your God require of you ,
&c.] For all these favours bestowed upon them, the forgiveness of their sins, and a fresh intimation of their possession of the land of Canaan, and the renewal of the promise of it made to their fathers:

but to fear the Lord your God ;
to fear him with a filial fear, to fear him and his goodness, and him for his goodness sake, and particularly for his pardoning grace and mercy vouchsafed to them; see (Psalms 130:4) ,

to walk in all his ways ;
prescribed and directed to by him, every path of duty, whether moral, ceremonial, or judicial:

and to love him, and to serve the Lord your God with all your heart, and
with all your soul ;
for that is the best service which springs from love, and love constrains unto, and which is hearty and sincere, as that is, and is performed in the best manner such are capable of.
