The point I was trying to get across was that it seems to me that in old times, mental illness was looked at in terms of demons etc.
There was one instance I can think of, where King Saul was tormented by a spirit. His symptoms resembled mental illness.
But there were also cases of depression that were not attributed to spirits -- notice how melancholy Solomon gets in his later writings...
Ec 1:2
Vanity of vanities! All is vanity.
Elijah's suicidal thoughts --
1Ki 19:4
But he himself went a day's journey into the wilderness, and came and sat down under a juniper tree; and he requested for himself that he might die, and said, "It is enough; now,
O Lord, take my life, for I am not better than my fathers."
Job's despair:
Job 9:21
I am guiltless; I do not take notice of myself;
I despise my life.
Jonah feeling trapped in hostility, fear and discouragement....
Jonah 4:3
Therefore now, O Lord, please take my life from me, for
death is better to me than life.
And actions of mourning or repentance...
Jer 48:37
For every head is bald and every beard cut short; there are
gashes on all the hands and sackcloth on the loins.
Jeremiah 41:5
The second day after he had killed Gedaliah; and no one knew, men from Shechem came from Shiloh, and from Samaria, eighty men, having their beards shaved, and their clothes torn, and having cut themselves, and with offerings and incense in their hand, to bring to the house of Jehovah.
Jeremiah 47:5
Baldness has come upon Gaza; Ashkelon has been ruined. O remnant of their valley, How long will you gash yourself?
And you know about Samson, the guy with the hair... I think he had a cracking point.
29
Samson grasped the two middle pillars on which the house rested, and braced himself against them, the one with his right hand and the other with his left.
And Samson said,
"Let me die with the Philistines!" And he bent with all his might so that the house fell on the lords and all the people who were in it. So the dead whom he killed at his death were more than those whom he killed in his life.
Most of these stories lack commentary, so there isn't discussion about why people acted how they did, or whether it was approved of God, or whether they were unstable.
I think that there are many times the Bible just recognizes that we are emotional beings who make decisions that aren't always wise, but reflect human passion, despair, loyalty, revenge...whatever. The history was what it was.
