Hebrews 13:9
9 Some people teach all kinds of strange new things. Do not let them lead you away from God's true message. It is good that God is very kind to us. That is what makes us strong inside ourselves. Rules about what foods we should eat do not make us strong like that. Those rules have never helped the people who tried to obey them.
13:9Some people were teaching that Christians should obey the Jewish rules about food.
