Midrash su Salmi 34:20

David forthwith arose and gathered together all the elders of Israel and the nobles, and they crossed the Jordan. They came to Jabesh-Gilead and they found the bones of Saul and Jonathan his son. No worm had been able to touch them, as it is said, "He keepeth all his bones, not one of them is broken" (Ps. 34:20). They took the bones of Saul and Jonathan his son, and placed them in a coffin, and they crossed the Jordan, as it is said, "And they buried the bones of Saul and Jonathan his son… and they performed all that the king commanded" (2 Sam. 21:14). The king commanded that they should bring the coffin of Saul in all the borders of each tribe. And it came to pass that the tribe || wherein they brought the coffin of Saul, the people (there) with their wives and their sons and their daughters came forth and displayed loving-kindness to Saul and to his sons, so that all Israel should discharge their obligation of showing loving-kindness. And thus (did they do) until it came to the border of his possession to the border of Jerusalem, in the land of Benjamin in Jerusalem, as it is said, "And they buried the bones of Saul and Jonathan his son in the country of Benjamin" (ibid.), in the vicinity of Jerusalem. When the Holy One, blessed be He, saw that all Israel had displayed loving-kindness (to him), He was forthwith full of compassion, and He sent rain upon the land, as it is said, "And after that God was intreated for the land" (ibid.).
