New Defender's Study Bible Notes
2:9 modest apparel. The “men” (literally “males,” not men in a generic sense) are to lead in public prayer, but only if in right standing before God. Women are to pray “in like manner also,” but in silent agreement, rather than leading the congregation. Further, they are to be dressed modestly—that is, decorously, neatly and pleasantly—but not in such a way as to draw special attention to themselves and their appearance.
2:9 shamefacedness. Originally “shamefastness,” which meant modest mien or reverence.
