'Until' in the Bible

Why then the law? It was added on account of transgressions, until the descendant should come to whom it had been promised, having been ordered through angels by the hand of a mediator.

But before faith came, we were detained under the law, imprisoned until the coming faith was revealed.

So then, the law became our guardian until Christ, in order that we could be justified by faith.

but he is under guardians and managers until the time set by [his] father.

My children, for whom I am having birth pains again, until Christ is formed in you!
