Esther 4:17e

Queen Esther also, being in dire fear of death, sought refuge in the Lord; and having removed her rich apparel, she put on garments of anguish and mourning. And instead of precious perfumes, she covered her head with ashes and dung. And she humbled her body greatly; and in every place of her [former appearance in] finery, she strewed with locks of her hair. And she turned to the Lord God of Israel, saying:

But I have done this, that I might not set the glory of man above the glory of God: and I will not worship any one except thee, my Lord, and I will not do these things in haughtiness.
