Galatians 4:8

Howbeit at that time, not knowing God, ye were in bondage to them that by nature are no gods:

Formerly, when you did not know God, you were slaves to those who by nature are not gods.

But then indeed, not knowing God, ye were in bondage to those who by nature are not gods;

But then indeed, not knowing God, you served them, who, by nature, are not gods.

At the time when you didn't know God, you were enslaved by the supposed “gods” of this world.

But euen then, when ye knewe not God, yee did seruice vnto them, which by nature are not gods:

Howbeit then, when ye knew not God, ye did service unto them which by nature are no gods.

But, formerly, when you did not have da'as [(knowledge)] of Hashem, you were avadim serving that which is by nature not HaEl Ha'Amiti [(the true G-d)].
