'Part' in the Bible

but only one thing is necessary, for Mary has chosen the good part, which shall not be taken away from her.”

If therefore your whole body is full of light, with no dark part in it, it will be wholly illumined, as when the lamp illumines you with its rays.”

For just like the lightning, when it flashes out of one part of the sky, shines to the other part of the sky, so will the Son of Man be in His day.
