15When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) 16Then let them which be in Judaea flee into the mountains: 17Let him which is on the housetop not come down to take any thing out of his house:

What does stand in the holy place mean?

Dan 12

11And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days. 12Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
