'Walk' in the Bible

and Peter having seen, answered unto the people, 'Men, Israelites! why wonder ye at this? or on us why look ye so earnestly, as if by our own power or piety we have made him to walk?

and they are instructed concerning thee, that apostasy from Moses thou dost teach to all Jews among the nations, saying -- Not to circumcise the children, nor after the customs to walk;

these having taken, be purified with them, and be at expence with them, that they may shave the head, and all may know that the things of which they have been instructed concerning thee are nothing, but thou dost walk -- thyself also -- the law keeping.
