Deuteronomy 28:21

The LORD shall make the pestilence cleave unto thee, until he have consumed thee from off the land, whither thou goest to possess it.

Pestilence (cf. 1 Kings 8:37; Amos 4:10) - some fatal epidemic. There is no reason, however, to think that the plague, which is the great modern scourge of the East, is referred to.
