Charles Ellicott Commentary Romans 12:10

"In love of the brethren be tenderly affectioned one to another; in honor preferring one another;" — Romans 12:10 (ASV)

With brotherly love.—Better translated as in the margin, In love of the brethren (fellow Christians) be kindly affectioned. The word for “kindly affectioned” is specially used of the family relation, and is, therefore, appropriately applied to the brotherhood of the Christian family.

Preferring one another.—Rather, perhaps, anticipating one another. The Christian is to take the initiative, and show honour or respect to others without waiting for them to show it to him.
