righteousness
The garment is Scripture is a symbol of righteousness. In the bad ethical sense, it symbolizes self-righteousness (for example, (Isaiah 64:6); (Philippians 3:6-8) the best that a moral and religious man under law could do). In the good ethical sense, the garment symbolizes "the righteousness of God. . .upon all them that believe."
( See Scofield) - (Romans 3:21).
