'Walking' in the Bible

So now, O Lord, the God of Israel, let your word to your servant David, my father, come true, when you said, You will never be without a man to take his place before me on the seat of the kingdom of Israel; if only your children give attention to their ways, walking in my law, as you have done before me.

So that they may give you worship, walking in your ways, as long as they are living in the land which you gave to our fathers.

And he did what was right in the eyes of the Lord, walking in the ways of his father David, without turning to the right hand or to the left.
