'Troubling' in the Bible

for an angel of the Lord went down at certain seasons into the pool, and troubled the water: whosoever then first after the troubling of the waters stepped in was made whole, with whatsoever disease he was holden.

But when the Jews of Thessalonica had knowledge that the word of God was proclaimed of Paul at Beroea also, they came thither likewise, stirring up and troubling the multitudes.
