'Short' in the Bible

The revelation of Jesus Christ, which God gave him to show to his slaves [the things] which must take place in a short time, and communicated [it] [by] sending [it] through his angel to his slave John,

And to each one of them a white robe was given, and it was said to them that they should rest yet a short time, until [the number of] their fellow slaves and their brothers who were about to be killed as they [had been] were completed also.

Five have fallen, one is, the other has not yet come, and whenever he comes it is necessary [for] him to remain a short time.

and threw him into the abyss, and shut [it] and sealed [it] above him, in order that he could not deceive the nations again until the thousand years are completed. After these [things] it is necessary [for] him to be released [for] a short time.

And he said to me, "These words [are] faithful and true, and the Lord, the God of the spirits of the prophets, has sent his angel to show his slaves [the things] which must take place in a short time."
