'Infirm' in the Bible

infirm ones be healing, lepers be cleansing, dead be raising, demons be casting out -- freely ye did receive, freely give.

And Jesus having come forth, saw a great multitude, and was moved with compassion upon them, and did heal their infirm;

naked, and ye put around me; I was infirm, and ye looked after me; in prison I was, and ye came unto me.

and when did we see thee infirm, or in prison, and we came unto thee?

a stranger I was, and ye did not receive me; naked, and ye put not around me; infirm, and in prison, and ye did not look after me.

'Then shall they answer, they also, saying, Lord, when did we see thee hungering, or thirsting, or a stranger, or naked, or infirm, or in prison, and we did not minister to thee?
