Wisdom 16:6

6 they were troubled for a little while as a warning, and received a symbol of deliverance to remind them of your law's command.

Wisdom 16:6 In-Context

4 For it was necessary that upon those oppressors inescapable want should come, while to these others it was merely shown how their enemies were being tormented.
5 For when the terrible rage of wild animals came upon your people and they were being destroyed by the bites of writhing serpents, your wrath did not continue to the end;
6 they were troubled for a little while as a warning, and received a symbol of deliverance to remind them of your law's command.
7 For the one who turned toward it was saved, not by the thing that was beheld, but by you, the Savior of all.
8 And by this also you convinced our enemies that it is you who deliver from every evil.
