Galatians 4:10

10 You are observing special days, and months, and seasons, and years.

Galatians 4:10 In-Context

8 Formerly, when you did not know God, you were enslaved to beings that by nature are not gods.
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? 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.
12 Friends, I beg you, become as I am, for I also have become as you are. You have done me no wrong.
