Hebrews 13:9

9 Do not be carried away by all kinds of strange teachings. It is good for our hearts to be strengthened by grace, not by eating ceremonial foods, which is of no benefit to those who do so.

Read Hebrews 13:9 Using Other Translations

Be 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.
Do not be led away by diverse and strange teachings, for it is good for the heart to be strengthened by grace, not by foods, which have not benefited those devoted to them.
So do not be attracted by strange, new ideas. Your strength comes from God’s grace, not from rules about food, which don’t help those who follow them.
