'Says' in the Bible

If anyone says to you, 'Why are you doing this?' say, 'The Lord needs it and will send it back here soon.'"

I tell you the truth, if someone says to this mountain, 'Be lifted up and thrown into the sea,' and does not doubt in his heart but believes that what he says will happen, it will be done for him.

Then if anyone says to you, 'Look, here is the Christ!' or 'Look, there he is!' do not believe him.

Wherever he enters, tell the owner of the house, 'The Teacher says, "Where is my guest room where I may eat the Passover with my disciples?"'
