and I will give them one heart and one way, that they may fear me for ever, for the good of them, and of their children after them:

I will give them one heart and one way, so that they will always fear Me for their own good and for the good of their children after them.

and I have given to them one heart, and one way, to fear Me all the days, for good to them, and to their sons after them:

And I will give them one heart, and one way, that they may fear me all [their] days, for the good of them, and of their children after them.
