Judith 5:17LXX

15There bitter fountains were made sweet for them to drink, and for forty years they received food from heaven.

16Wheresoever they went in without bow and arrow, and without shield and sword, their God fought for them and overcame.

17And there was no one that triumphed over this people, but when they departed from the worship of the Lord their God.

18But as often as beside their own God, they worshipped any other, they were given to spoil, and to the sword, and to reproach.

19And as often as they were penitent for having revolted from the worship of their God, the God of heaven gave them power to resist.
