Riverside(i)
7 So you are no longer a slave, but a son, and if a son, then also an heir, through God's act.
8 At the time when you did not know God you were enslaved to what by nature are not gods.
9 But now that you know God, or rather have been known by God, how are you turning back to the weak and beggarly elementary lessons to which you wish to be slaves again?
10 You observe days and months and seasons and years.
