give the sword you want to glow the instance name "sword"
import flash.filters.GlowFilter;
var swordglow:GlowFilter=new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout);
sword.filters=[gf];
change color, alpha, blurX, blurY, strength and quality to numbers, ofcourse color is "0x" + hexidecimal number, and inner and knockout are boolean (true/false)
a sample for a red glow:
import flash.filters.GlowFilter;
var swordglow:GlowFilter=new GlowFilter(0xFF0000, 100, 10, 10, 2, 3, true, false);
sword.filters=[gf];
