'Trouble' in the Bible

And Jesus went with them. And when he was now not far from the house, the centurion sent friends to him, saying unto him, Lord, trouble not thyself; for I am not worthy that thou shouldest come under my roof:

While he yet spake, there cometh one from the ruler of the synagogue's house , saying, Thy daughter is dead; trouble not the Teacher.

and he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee?
