'Rejoice' in the Bible

And Hannah prayed, and said, My heart exulteth in Jehovah, my horn is lifted up in Jehovah; my mouth is opened wide over mine enemies; for I rejoice in thy salvation.

for he put his life in hand, and smote the Philistine, and Jehovah wrought a great salvation for all Israel: thou didst see it, and didst rejoice; why then wilt thou sin against innocent blood, in slaying David without cause?
