Wisdom 16:6

6 This trouble lasted for only a little while, as a warning. Then you gave them a healing symbol, the bronze snake, to remind them of what your Law requires.

Wisdom 16:6 In-Context

4 It was necessary for the oppressors to suffer relentless need, while your people saw how their enemies were being tormented.
5 When terrible, fierce snakes attacked your people and were killing them with their poison, you did not remain angry long enough to destroy your people.
6 This trouble lasted for only a little while, as a warning. Then you gave them a healing symbol, the bronze snake, to remind them of what your Law requires.
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.
