Wisdom 5:18 In-Context

16 Therefore they will receive a glorious crown and a beautiful diadem from the hand of the Lord, because with his right hand he will cover them, and with his arm he will shield them.
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.
