Easton's Bible Dictionary (1897)/Boil

Boil
 * Boil (rendered "botch" in Deut. 28:27, 35), an aggravated ulcer, as in the case of Hezekiah (2 Kings 20:7; Isa. 38:21) or of the Egyptians (Ex. 9:9, 10, 11; Deut. 28:27, 35). It designates the disease of Job (2:7), which was probably the black leprosy.
