Three and a half
In Revelation 11:9, this signifies to the end and the beginning, or to the end of the present church and the beginning of a new church. (Apocalypse Revealed 505) It also signifies the same as a week because it is half of seven. (Apocalypse Revealed 505[2])
Revelation 11:9
9
From among the peoples, tribes, languages, and nations people will look at their dead bodies for three and a half days, and will not allow their dead bodies to be laid in a tomb.
