20 His severe wrath shall he sharpen for a sword, and the world shall fight with him against the unwise.

Wisdom 5:20 In-Context

18 He shall put on righteousness as a breastplate, and true judgment instead of an helmet.
19 He shall take holiness for an invincible shield.
20 His severe wrath shall he sharpen for a sword, and the world shall fight with him against the unwise.
21 Then shall the right aiming thunderbolts go abroad; and from the clouds, as from a well drawn bow, shall they fly to the mark.
22 And hailstones full of wrath shall be cast as out of a stone bow, and the water of the sea shall rage against them, and the floods shall cruelly drown them.
