'On the Sabbath' in the Bible

He commanded them, saying, "This [is] the thing which you must do: one third of you {who go off duty on the Sabbath}, the keepers of the guard in the house of the king,

Two of the units among you, all {who go on duty on the Sabbath}, guard the post of the temple of Yahweh for the king.

So the commanders of hundreds did according to all that Jehoiada the priest commanded, and each took his men {who went off duty on the Sabbath} and those {who came on duty on the Sabbath}, and they came to Jehoiada the priest.
