'Walk' in the Bible

Wherefore the LORD God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the LORD saith, Be it far from me; for them that honour me I will honour, 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 mine heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever.

And 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.
