And Hannah prayed, and said: My heart exulteth in Jehovah; My horn is exalted in Jehovah; My mouth is enlarged over mine enemies; Because I rejoice in thy salvation.

for he put his life in his hand, and smote the Philistine, and Jehovah wrought a great victory for all Israel: thou sawest it, and didst rejoice; wherefore then wilt thou sin against innocent blood, to slay David without a cause?
