Wisdom 16:9

9 Our enemies died from the bites of locusts and flies; no way was found to cure them, because they deserved to be punished by such creatures.

Wisdom 16:9 In-Context

7 If a person looked at that symbol, he was cured of the snakebite - not by what he saw, but by you, the savior of all mankind.
8 By doing this, you also convinced our enemies that you are the one who rescues people from every evil.
9 Our enemies died from the bites of locusts and flies; no way was found to cure them, because they deserved to be punished by such creatures.
10 But even poisonous snakes could not overcome your people, because you had mercy, helped them, and cured them.
11 They were bitten so that they would remember your commands, but they were quickly rescued, in order to keep them from forgetting you completely and depriving themselves of your kindness.
