'Newborn' in the Bible

She will eat her afterbirth and her newborn children secretly since there will be nothing left on account of the siege and distress with which your enemy will oppress you in your cities."

So he went down and plunged himself into the Jordan River seven times, just as the man of God had said, and his flesh rejuvenated like the flesh of a newborn child. And he was clean.

Like newborn babies, thirst for the pure milk of the word so that by it you may grow in your salvation.
