2 Samuel 21:10

Rizpah … took sackcloth, and spread it for her upon the rock; rather, against the rock, so as to form a little hut or shelter to protect her from the glaring blaze of the sunshine. The word "upon" has led many commentators to suppose that she used it as a bed; but this is not the meaning of the Hebrew, though given by the Vulgate. The sackcloth was the loose wrapper or cloak which formed the outer dress of mourners. As regards the bodies of those crucified or impaled, the Law required that they should be taken down and buried that same evening ( Deuteronomy 21:23 ). Here they remained exposed for six months, as a grim trophy of Gibeonite vengeance. Until water dropped upon them out of heaven; Hebrew, was poured upon them; until copious and heavy rains came. The outpouring of these rains would put an end to the famine, and be regarded as a proof that the wrath of Heaven was appeased. There is no reason for supposing that these rains came before the usual period, in autumn, which was about the middle of October. Thus, for six months, with no other protection than her mantle of sackcloth hung against the rock, this noble woman watched the decaying bodies of her loved ones, until at last her devoted conduct touched David's heart, and their remains were honourably interred.
