Wisdom 5:19

19 he will take holiness as an invincible shield,

Wisdom 5:19 In-Context

17 The Lord will take his zeal as his whole armor, and will arm all creation to repel his enemies;

18 he will put on righteousness as a breastplate, and wear impartial justice as a helmet;

19 he will take holiness as an invincible shield,

20 and sharpen stern wrath for a sword, and creation will join with him to fight against the madmen.

21 Shafts of lightning will fly with true aim, and will leap to the target as from a well-drawn bow of clouds,
