'Waited' in the Bible

And they ministered before the dwelling place of the tabernacle of the congregation with singing, until Solomon had built the house of the LORD in Jerusalem: and then they waited on their office according to their order.

And these are they that waited with their children. Of the sons of the Kohathites: Heman a singer, the son of Joel, the son of Shemuel,

Who hitherto waited in the king's gate eastward: they were porters in the companies of the children of Levi.
