'Until' in the Bible

Until certain people came from James, he had been eating with the Gentiles. But when they arrived, he stopped doing this and separated himself because he was afraid of those who were pro-circumcision.

Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.

Now before faith came we were held in custody under the law, being kept as prisoners until the coming faith would be revealed.

Thus the law had become our guardian until Christ, so that we could be declared righteous by faith.

But he is under guardians and managers until the date set by his father.

My children -- I am again undergoing birth pains until Christ is formed in you!
