Deuteronomy 6:18 Meaning and Commentary

Deuteronomy 6:18

And thou shalt do that which is right and good in the sight of

and that thou mayest go in and possess the good land which the Lord
sware unto thy fathers;
to give to them and to their posterity, even the land of Canaan; but if they did not what was right and good in the sight of God, they might expect to be kept out of it, as their immediate parents were, whose carcasses fell in the wilderness.
