'Waited' in the Bible

And they ministered with song before the tabernacle of the tent of meeting, until Solomon had built the house of Jehovah in Jerusalem: and they waited on their office according to their order.

And these are they that waited, and their sons. Of the sons of the Kohathites: Heman the singer, the son of Joel, the son of Samuel,

who hitherto waited in the king's gate eastward: they were the porters for the camp of the children of Levi.
