Midrash su Salmi 58:9

[(Gen. 19:24:) THEN THE LORD RAINED DOWN UPON SODOM.] This text is related (to Ps. 58:9 [8]): LET THEM BE LIKE A SNAIL (ShBLWL),< WHICH DISSOLVES AND GOES AWAY; LIKE A WOMAN'S STILLBIRTH, THEY HAVE NOT SEEN THE SUN >.⁶⁶Cf. Gen. R. 51:1. [Just as a flood stream (ShBLT) is swept away, so were the people of Sodom swept away. WHICH DISSOLVES AND GOES AWAY], in that the Holy One dissolved them in fire. LIKE A WOMAN'S STILLBIRTH, THEY HAVE NOT SEEN THE SUN, in that the people of Sodom did not see < it any more >, as stated (in Gen. 19:23): THE SUN HAD RISEN OVER THE EARTH < WHEN LOT CAME TO ZOHAR >. What < else > is written there (in vs. 24)? THEN THE LORD RAINED DOWN UPON SODOM < AND UPON GOMORRAH BRIMSTONE AND FIRE >.

Another interpretation (of Ps. 58:9 [8]): What is the meaning of LIKE A SNAIL (ShBLWL)? Just as a flood stream (ShBLT) sweeps away whatever it comes upon, so it is with a rioter⁶⁷Gk.: thorubos (tumult). who rises up in a region. Anyone who is found with him is swept away with him. Thus it is stated: LIKE A SNAIL (ShBLWL). And when he is dead, he no longer sees the sun (cf. ibid., cont.)⁶⁸Jastrow, s.v. toribos, translates the clause, “he faces no more the sun (his body is not exhibited for public honors).” Why? Because he was a rioter.
