What is a…
boil

This is an aggravated ulcer, as in the case of Hezekiah (2 Kings 20:7; Isaiah 38:21) or of the Egyptians (Exodus 9:9-11; Deuteronomy 28:27, 35).

This word is translated “botch” in Deuteronomy 28:27, 35.

It designates the disease of Job (2:7), which was probably the black leprosy.
