'Uneasy' in the Bible

“Therefore I tell you, stop being worried or anxious (perpetually uneasy, distracted) about your life, as to what you will eat or what you will drink; nor about your body, as to what you will wear. Is life not more than food, and the body more than clothing?

But he who is uncertain [about eating a particular thing] is condemned if he eats, because he is not acting from faith. Whatever is not from faith is sin [whatever is done with doubt is sinful].
