Galatians 4:9-11

New Revised Standard Version, Anglicised

⁹ Now, however, that you have come to know God, or rather to be known by God, how can you turn back again to the weak and beggarly elemental spirits?^[a] How can you want to be enslaved to them again? ¹⁰ You are observing special days, and months, and seasons, and years. ¹¹ I am afraid that my work for you may have been wasted.
