The proverb ‘charity begins at home’ expresses the overriding demand to take care of one’s family, before caring for others.

‘Charity begins at home’ isn’t from the bible but it is so near to being so that it is reasonable to describe it as biblical. The notion that a man’s family should be his foremost concern is expressed in 1 Timothy 5:8, King James Bible, 1611:

But if any provide not for his owne, & specially for those of his owne house, hee hath denied the faith, and is worse then an infidel.
