12:10

brotherly love: The Greek term phi·la·del·phiʹa literally means “affection for a brother.” Paul uses it three times​—at Ro 12:10, at 1Th 4:9, and at Heb 13:1. Peter uses this term three times in his letters (once at 1Pe 1:22 and twice at 2Pe 1:7), where it is rendered “brotherly affection.” The use of this term by Paul and Peter indicates that relationships among Christians should be as close, strong, and warm as in a natural family.

have tender affection: The Greek word used here, phi·loʹstor·gos, is a compound word composed of two terms that denote love and affection. The root word sterʹgo denotes a natural affection, as between family members. The second term is related to phiʹlos, a close friend. (Joh 15:13-15) The combination of these terms denotes a strong affection as shown in a family. In fact, both words used in this context (phi·la·del·phiʹa, rendered “brotherly love,” and phi·loʹstor·gos, rendered “tender affection”) refer to affection that should naturally be shown among family members. Such is the level of love and affection that Paul is urging fellow Christians to show toward one another.​—See study note on brotherly love in this verse.

take the lead: Or “take the initiative.” The Greek word pro·e·geʹo·mai appears only here in the Christian Greek Scriptures. It literally means “to go before,” and in this context, it denotes an eagerness to show honor to others. In first-century Greek, Jewish, and Roman society, people made every effort to gain honor for themselves. (Lu 20:46) Here Paul expresses a contrary view, namely, that Christians should make every effort to show honor and respect for others. In fact, some suggest that this expression implies trying to outdo one another in showing honor to others.
