1 Samuel 21:2

David said to Ahimelech the priest, “The king has commanded me to do something, and has said to me, ‘Let no one know anything about the business about which I send you, and what I have commanded you. I have sent the young men to a certain place.’

And David said unto Ahimelech the priest, The king hath commanded me a business, and hath said unto me, Let no man know any thing of the business whereabout I send thee, and what I have commanded thee: and I have appointed my servants to such and such a place.
