But when they bring you before the synagogues and the rulers and the authorities, do not be anxious how or what you should speak in your own defense or what you should say,

And he said to his disciples, "For this [reason] I tell you, do not be anxious for [your] life, what you will eat, or for [your] body, what you will wear.

And which of you [by] being anxious is able to add an hour to his life span?

If then you are not even able [to do] a very little thing, why are you anxious about the rest?

And you, do not consider what you will eat and what you will drink, and do not be anxious.
