'Long' in the Bible

That very hour the order about Nebuchadnezzar was put into effect: and he was sent out from among men, and had grass for his food like the oxen, and his body was wet with the dew of heaven, till his hair became long as eagles' feathers and his nails like those of birds.

Then there came to my ears the voice of a holy one talking; and another holy one said to that certain one who was talking, How long will the vision be while the regular burned offering is taken away, and the unclean thing causing fear is put up, and the holy place crushed under foot?

And those who are wise among the people will be the teachers of the mass of the people: but they will come to their downfall by the sword and by the flame, being made prisoners and undergoing loss for a long time.

And I said to the man clothed in linen, who was over the waters of the river, How long will it be to the end of these wonders?
