הלכה על ישעיהו 38:16

One who is occasionally SICK (meaning, healthy, as in "and you have healed me and enlivened me" in Isaiah 38:16)), and occasionally foolish when SICK, he is considered sharp-sighted for all his words. And if under this condition he expels his wife, that expulsion is considered a valid divorce. Even if he is SICK unknowingly, and not completely sane. See above mark 119 verse 6.
