What does 1 Samuel 14:45 mean?

But the people stepped in and said to Saul, 'Should Jonathan die? He’s the one who brought this victory to Israel! No way. As surely as the Lord lives, not a hair on his head will be harmed. God worked through him today.' So the people rescued Jonathan, and he wasn’t put to death. 1 Samuel 14:45 - Modern Text Bible
