In some examples the nature of the disease is specified, as Asa's disease in his feet (), for which he sought the aid of physicians in vain (). Hezekiah and Job suffered from sore boils, Jehoram from some severe dysenteric attack (), as did Antiochus Epiphanes (2 Macc 9:5). Probably the sudden and fatal disease of Herod was similar, as in both cases there is reference to the presence of worms (compare and 2 Macc 9:9). The disease of Publius' father was also dysentery (). Other diseases specified are paralysis (; ), and fever (). Not improbably the sudden illness of the young Egyptian at Ziklag (), and the illness of Ben-hadad which weakened him so that he could not resist the violence of Hazael, were also the common Palestine fever () of whose symptoms and effects there is a graphic description in Ps 38. Unspecified fatal illnesses were those of Elisha (), Lazarus (), Tabitha (). In the language of the Bible, leprosy is spoken of as a defilement to be cleansed, rather than as a disease to be cured.
The proverb concerning the sick quoted by the Lord at Capernaum () has come down to us in several forms in apocryphal and rabbinical writings (Bābhā' Ḳammā' 26:13; Ṣanhedhrı̄n 176), but is nowhere so terse as in the form in which He expresses it. The Lord performed His healing of the sick by His word or touch, and one of the most emphatic charges which He gave to His disciples when sending them out was to heal the sick. One of the methods used by them, the anointing with oil, is mentioned in and enjoined by James (). In later times the anointing which was at first used as a remedial agent became a ceremonial in preparation for death, one of the seven sacraments of the Roman church (Aquinas, Summa Theologia suppl. ad Piii. 29).
The duty of visiting the sick is referred to in , , and by the Lord in the description of the Judgment scene (, ). It is inculcated in several of the rabbinical tracts. “He that visits the sick lengthens his life, he who refrains shortens it,†says Rabbi Ischanan in Nedhārı̄m 29. In Shulḥan ‛Arūkh, Yōreh Dē‛āh there is a chapter devoted to this duty, which is regarded as incumbent on the Jew, even though the sick person be a Gentile (Giṭṭı̄n 61a). The church's duty to the sick, so long neglected, has, within the last century, been recognized in the mission field, and has proved, in heathen lands, to be the most important of all pioneer agressive methods.
While we find that the apostles freely exercised their gifts of healing, it is noteworthy that we read of the sickness of two of Paul's companions, Epaphroditus () and Trophimus (), for whose recovery he seems to have used no other means than prayer. See also DISEASE.
