2 Samuel 21:10

And Rizpah, the daughter of Aiah, the mother of two of the hanged men, took sackcloth, the usual garment of mourners, and spread it for her upon the rock, to serve as her bed, from the beginning of harvest until water dropped upon them out of heaven, until the falling of rain some time during the summer indicated that the anger of God was appeased, and suffered neither the birds of the air to rest on them by day nor the beasts of the field by night. This being a case where the bodies mere to serve as a sign of expiation, they were not taken do-m from the stakes in the evening, Deuteronomy 21:22. Since ravenous birds and beasts were not permitted to come near the bodies, they probably dried out quickly.
