Enderûn (Ottoman Turkish: اندرون, from Persian andarûn, "inside") was the term used in the Ottoman Empire to designate the "Interior Service" of the Imperial Court, concerned with the private service of the Ottoman Sultans, as opposed to the state-administrative "Exterior Service" (Birûn). Its name derives from the location of the Sultan's apartments in the inner courts of the Topkapi Palace; its head was the Kapi Agha.
The Inner Service was divided into four departments. In descending order of importance, these were the Privy Chamber (Hass Oda), the Treasury (Hazine), the Privy Larder (Kilar-ı Hass), and the Great and Little Chambers (Büyük ve Küçük Odalar). Among the responsibilities of the Inner Service was also the running of the palace school, where selected young Christian boys, gathered through the devşirme system (from the 17th century, however, Muslim boys were also admitted) were trained for the highest state offices. These boys served then as pages in the Inner Service, and were known as içoğlanı ("lads of the interior").
Hold on to life for all you're worth
You know He died for all you're worth
He loves you
You have the greatest value
He gave His life for all
For all you're worth
By this time you know the story
There's nothing there you haven't heard
You can cross the line of knowing
And your heart believing His Word
Do you think He brought you this far
Just to leave you wondering where and who you are
Just think back to where it began
Jesus called your name and then you just took His Hand
Hold on to life for all you're worth
You know He died for all you're worth
He loves you
You have the greatest value
He gave His life for all
For all you're worth
Even gold still needs refining
Burning off impurities
Even diamonds grow in value
When they're cut so carefully
There's no life beyond His repair
You will find Him waiting just beyond a prayer
He invested all that He had
Don't you think it hurts Him inside to see you sad
Hold on to life for all you're worth
You know He died for all you're worth
He loves you
You have the greatest value
He gave His life for all
For all you're worth
He has His eye on you
You have the greatest value
He gave His life or all
For all you're worth
