Midrash su Salmi 57:3

And Jacob called unto his sons. Scripture states elsewhere in allusion to this verse: I will cry unto God Most High; unto God that accomplisheth it for me (Ps. 57:3). R. Joshua the son of Levi said: The earthly court promulgated three decrees. And these are they: the first occurred during the time of Ezra. After their return from Babylon, the Holy One, blessed be He, desired them to release the Israelites from the obligation of giving tithes.¹³Because they were impoverished, and the tithe demanded too great a sacrifice. What did the Israelites do? They arose and decreed that they would pay their tithes, as it is said: And that we should bring the first of our dough, and our heave-offerings, and the fruit of all manner of trees, the wine and the oil, unto the priests, to the chambers of the house of our God; and the tithes of our land unto the priests (Neh. 10:38). What did they do after that? They recorded this decree in a book, signed it, and placed it in the Temple. When they entered the Temple the next day, they found that it had been sealed. Whence do we know this? It is written: And yet for all this we make a sure covenant, and subscribe it, and seal it (ibid., v. 1). Because it had been sealed they knew that the Holy One, blessed be He, approved their decision.

... “And David went and he took the bones of Saul and the bones of Jonathan his son from the men of Jabesh- gilead… And he brought up from there the bones of Saul and the bones of Jonathan his son…” (Shmuel II 21:12-13) What did David do? He went and gathered all the elders and great ones of Israel, crossed the Jordan River, and came to Yavesh-gilead. He found the bones of Shaul and his son Yonatan, placed them in a casket and crossed back over the Jordan, as it says “And they buried the bones of Saul and Jonathan his son in the country of Benjamin in Zela, in the tomb of Kish his father and they did all that the king commanded…” (Shmuel II 21:14) What does ‘in Zela, in the tomb of Kish his father’ mean? It comes to teach us that they brought them to the border of Jerusalem and buried them there. Zela is next to Jerusalem, as it says “And Zelah, Eleph, and the Jebusite, which is Jerusalem…” (Yehoshua 18:28) ‘and they did all that the king commanded’ And what did the king command? He commanded that they carry Shaul’s casket from tribe to tribe. As Shaul’s casket entered each tribe’s territory all the men, women and children came out in order to perform an act of loving kindness to Shaul and his sons and thereby all of Israel would fulfill its obligation to loving kindness. This went on until they reached the land of his portion on the border of Jerusalem. Since the Holy One saw that they did loving kindness to Shaul and fulfilled the judgement of the Givonites He was immediately filled with mercy and sent rain upon the land, as it says “And God was entreated for the land after that.” (Shmuel II 21:14) From this we learn how close the Holy One brings those that are far away, even though they converted not for the sake of heaven. There is no need to even mention how he draws near righteous converts, “O Lord, all the kings of the earth will acknowledge You…” (Tehillim 138:4)

Another interpretation (of Gen. 49:1): THEN JACOB CALLED HIS SONS. This text is related (to Ps. 57:3 [2]): I SHALL CALL TO GOD MOST HIGH, TO THE GOD WHO BRINGS THINGS TO COMPLETION FOR MY BENEFIT. R. Joshua ben Levi said: An earthly court has decreed three things when the Holy One has concurred with them.⁴⁰Gen. R. 96, New Version, on Gen. 49:1 (= pp. 1202—1204 in the Theodor-Albeck edition); cf. yBer. 5:8 (or 9) (14c); Mak. 23b; Ruth R. 4:5; M. Pss. 57:2; cf. also Matthew 16:19. They are the following:
