'Ward' in the Bible

and they laid hands on them, and put them in ward till the morrow; for it was already evening.

and laid hands on the apostles, and put them in public ward.

When they were past the first and the second ward, they came unto the iron gate that leadeth unto the city; which opened to them of his own accord: and they went out, and passed on through one street; and forthwith the angel departed from him.

But before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed.
