So, if you recognize that Paul means he was [Past Tense] detained by ‘working six days per week’, imprisoned by ‘woking six days per week’ UNTIL the coming faith was reveled, then basically Paul moved on past ‘working six days per week’ once the faith was revealed. (i.e. He’s observing the Sabbath Rest, since he (and we also) since we are no longer detained/imprisoned by ‘working six days per week’.
I mean, in a very clear sense, Gal 3:23 is telling us:
Galatians 3:23 (LEB) But before faith came, we were detained under the law, imprisoned until the coming faith was revealed.
But before faith came, we were detained under Ex 20:9, imprisoned until the coming faith was revealed.
But before faith came, we were detained under ‘working six days per week’, imprisoned until the coming faith was revealed.
But before faith came , we were kept under the law, shut up unto the faith which should afterwards be revealed .
24Wherefore the law was our schoolmaster to bring us untoChrist, that we might be justified by faith.
But after that faith is come , we are no longer under a schoolmaster. Galatians 3:23-25
The law of Moses kept the children of Israel "guarded" against transgressing God's (Abrahamic) Covenant Law as a fence guards against transgressing the boundries of a property.
What purpose then does the law serve?....It was added because of transgressions, till the Seed should come to whom the promise was made; Galatians 3:19
Like a fence is "added" to guard against the transgression of property boundries, the law was added to protect the natural offspring of Abraham from transgressing the boundaries of of the Abrahamic Covenant, SO THAT...
God could continue to bless them with the blessing of Abraham, which included God's protection from their enemies.
God couldn't bless Covenant Breakers (transgressors) and without His blessing upon the children of Israel they couldn't defeat the Giants and fulfill God's promise to Abraham to give his decendants the "Promised Land".
No Blessing, No Ability to drive out the Giants from the land God promised to give Abraham's decendants!!!
