Hebrews 13:7-9

7Remember them which have the rule over you, who have spoken unto you the word of God: whose faith follow, considering the end of their conversation.

8Jesus Christ the same yesterday, and to day, and for ever.

9Be not carried about with divers and strange doctrines. For it is a good thing that the heart be established with grace; not with meats, which have not profited them that have been occupied therein.
