'Ward' in the Bible

And the chief Levites: Hashabiah, Sherebiah, and Jeshua the son of Kadmiel, with their brethren over against them, to praise and to give thanks, according to the commandment of David the man of God, ward over against ward.

Mattaniah and Bakbukiah, Obadiah, Meshullam, Talmon, Akkub, were doorkeepers keeping the ward at the storehouses of the gates.

And, with the singers and the doorkeepers, they kept the ward of their God, and the ward of the purification, according to the commandment of David and of Solomon his son.

And he cried as a lion, Lord, I stand continually upon the watchtower in the daytime, and I am set in my ward whole nights.

But evil shall come upon thee thou shalt not know from whence it riseth; and mischief shall fall upon thee, which thou shalt not be able to ward off; and desolation that thou suspectest not shall come upon thee suddenly.

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