2 Samuel 13:5

And Jonadab said unto him, Lay thee down on thy bed and make thyself sick, feigning illness; and when thy father cometh to see thee, to visit the son who had been reported sick, say unto him, I pray thee, let my sister Tamar come and give me meat, prepare food, and dress them eat in my sight, make ready some special dish for the sick, that I may see it, and eat it at her hand. He intimated that the sight of the food in such circumstances would give him an appetite. Evidently every wife of the king with her children occupied her own apartments in the royal palace, but the intercourse between the children was fairly free.
