'Brother's' in the Bible

Be kind to one another with a brother's love, putting others before yourselves in honour;

But you, why do you make yourself your brother's judge? or again, why have you no respect for your brother? because we will all have to take our place before God as our judge.

Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.

The right course is to forego eating meat or drinking wine or doing anything that tends to your brother's fall.
