Sirach 7:17

17 Humble thyself greatly: for the vengeance of the ungodly is fire and worms.

Sirach 7:17 In-Context

15 Hate not laborious work, neither husbandry, which the most High hath ordained.
16 Number not thyself among the multitude of sinners, but remember that wrath will not tarry long.
17 Humble thyself greatly: for the vengeance of the ungodly is fire and worms.
18 Change not a friend for any good by no means; neither a faithful brother for the gold of Ophir.
19 Forego not a wise and good woman: for her grace is above gold.
