'Troubled' in the Bible

“Now My soul is troubled. What should I say—Father, save Me from this hour? But that is why I came to this hour.

When Jesus had said this, He was troubled in His spirit and testified, “I assure you: One of you will betray Me!”

“Your heart must not be troubled. Believe in God; believe also in Me.

“Peace I leave with you. My peace I give to you. I do not give to you as the world gives. Your heart must not be troubled or fearful.
