Wisdom 16:10

10 But thy sons not the very teeth of venomous dragons overcame: for thy mercy was ever by them, and healed them.

Wisdom 16:10 In-Context

8 And in this thou madest thine enemies confess, that it is thou who deliverest from all evil:
9 For them the bitings of grasshoppers and flies killed, neither was there found any remedy for their life: for they were worthy to be punished by such.
10 But thy sons not the very teeth of venomous dragons overcame: for thy mercy was ever by them, and healed them.
11 For they were pricked, that they should remember thy words; and were quickly saved, that not falling into deep forgetfulness, they might be continually mindful of thy goodness.
12 For it was neither herb, nor mollifying plaister, that restored them to health: but thy word, O Lord, which healeth all things.
