Wisdom 18:13

13 For though they had disbelieved everything because of their magic arts, yet, when their first-born were destroyed, they acknowledged thy people to be God's son.

Wisdom 18:13 In-Context

11 The slave was punished with the same penalty as the master, and the common man suffered the same loss as the king;
12 and they all together, by the one form of death, had corpses too many to count. For the living were not sufficient even to bury them, since in one instant their most valued children had been destroyed.
13 For though they had disbelieved everything because of their magic arts, yet, when their first-born were destroyed, they acknowledged thy people to be God's son.
14 For while gentle silence enveloped all things, and night in its swift course was now half gone,
15 thy all-powerful word leaped from heaven, from the royal throne, into the midst of the land that was doomed, a stern warrior
