Luke 14:16-18 (KJV)
16 Then said he unto him, A certain man made a great supper, and bade many:
17 And sent his servant at supper time to say to them that were bidden, Come; for all things are now ready.
18 And they all with one consent began to make excuse. The first said unto him, I have bought a piece of ground, and I must needs go and see it: I pray thee have me excused.
