Galatians 4:9-10

4:9 But now that you have come to know God (or rather to be known by God), how can you turn back again to the weak and worthless basic forces? Do you want to be enslaved to them all over again? 4:10 You are observing religious days and months and seasons and years.

Colossians 2:16-17

2:16 Therefore do not let anyone judge you with respect to food or drink, or in the matter of a feast, new moon, or Sabbath days – 2:17 these are only the shadow of the things to come, but the reality is Christ!
