So if your whole body is full of light, with no part of it in darkness, you will be radiant, as though a lamp were shining on you.”
KJV
If thy whole body therefore [be] full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light.
ASV
If therefore thy whole body be full of light, having no part dark, it shall be wholly full of light, as when the lamp with its bright shining doth give thee light.
