'Troubled' in the Bible

For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had.

The impotent man answered him, Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me.

When Jesus therefore saw her weeping, and the Jews also weeping which came with her, he groaned in the spirit, and was troubled,

Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour.

When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.

Let not your heart be troubled: ye believe in God, believe also in me.

Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
