Galatians 4:9-11

Young's Literal Translation

⁹ and now, having known God -- and rather being known by God -- how turn ye again unto the weak and poor elements to which anew ye desire to be in servitude?

¹⁰ days ye observe, and months, and times, and years!

¹¹ I am afraid of you, lest in vain I did labour toward you.
