'Standing' in the Bible

and I say to them, 'Let not the gates of Jerusalem be opened till the heat of the sun, and while they are standing by let them shut the doors, and fasten, and appoint guards of the inhabitants of Jerusalem, each in his guard, and each over-against his house.'

and the Tirshatha saith to them that they eat not of the most holy things till the standing up of the priest with Urim and Thummim.

And certain are appointed on that day over the chambers for treasures, for heave-offerings, for first-fruits, and for tithes, to gather into them out of the fields of the cities the portions of the law for priests, and for Levites, for the joy of Judah is over the priests, and over the Levites, who are standing up.
