Romans 14:5-6

Complete Jewish Bible

⁵ One person considers some days more holy than others, while someone else regards them as being all alike. What is important is for each to be fully convinced in his own mind. ⁶ He who observes a day as special does so to honor the Lord. Also he who eats anything, eats to honor the Lord, since he gives thanks to God; likewise the abstainer abstains to honor the Lord, and he too gives thanks to God.
