Revelation 8:10-11

Wycliffe Bible

¹⁰ And the third angel trumpeted; and a great star burning as a little brand, fell from heaven; and it fell into the third part of rivers, and into the wells of waters. [And the third angel sang in trump; and a great star burning as a brand, fell down from heaven; and it fell into the third part of floods, and into wells of waters.]

¹¹ And the name of the star is said Wormwood. And the third part of waters was made into wormwood; and many men were dead of the waters, for those were made bitter [for they be made bitter].
