Wisdom 5:17

17 He shall take to him his jealousy for complete armour, and make the creature his weapon for the revenge of his enemies.

Wisdom 5:17 In-Context

15 But the righteous live for evermore; their reward also is with the Lord, and the care of them is with the most High.
16 Therefore shall they receive a glorious kingdom, and a beautiful crown from the Lord's hand: for with his right hand shall he cover them, and with his arm shall he protect them.
17 He shall take to him his jealousy for complete armour, and make the creature his weapon for the revenge of his enemies.
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.
