'Walk' in the Bible

Therefore Jehovah, the God of Israel, saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now Jehovah saith, Be it far from me; for them that honor me I will honor, and they that despise me shall be lightly esteemed.

And I will raise me up a faithful priest, that shall do according to that which is in my heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever.

and they said unto him, Behold, thou art old, and thy sons walk not in thy ways: now make us a king to judge us like all the nations.
