'Infirmity' in the Bible

Speak unto the children of Israel, saying, If a woman have conceived seed, and born a man child: then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.

And I said, This is my infirmity: but I will remember the years of the right hand of the most High.

The spirit of a man will sustain his infirmity; but a wounded spirit who can bear?
