2 Samuel 9:10

9:10 You will cultivate the land for him – you and your sons and your servants. You will bring its produce and it will be food for your master’s grandson to eat. But Mephibosheth, your master’s grandson, will be a regular guest at my table.” (Now Ziba had fifteen sons and twenty servants.)
