מדרש על איוב 26:5

And all living things which were upon the face of the earth decayed, as it is said, "And every living thing was destroyed which was upon the face of the ground" (Gen. 7:23), except Noah and those who were with him in the ark, as it is said, "And Noah only was left, and they that were with him in the ark" (ibid.), except Og, king of Bashan, who sat down on a piece of wood under the gutter of the ark. He swore to Noah and to his sons that he would be their servant for ever. What did Noah do? He bored an aperture in the ark, and he put (through it) his food daily for him, and he also was left, as it is said, "For only Og, king of Bashan, remained of the remnant of the giants" (Deut. 3:11). (The Flood was universal) except in the land of Israel, upon which the water of the Flood did not descend from heaven, but the waters were gathered together from all lands, and they entered therein, as it is said, "Son of man, say unto her, Thou art a land that is not cleansed, nor rained upon, in the day of indignation" (Ezek. 22:24).

"Thou stretchedst out thy right hand, the earth swallowed them" (Ex. 15:12). The Holy One, blessed be He, told the earth to bury the slain. (The earth) said unto Him: Sovereign of all worlds! The waters have killed them, let the waters swallow them. He answered (the earth) saying: On this occasion receive them; on another occasion such that be killed by thee in the future will I cast into the sea, namely, Sisera and all his host, these will I cast into the sea, as it is said, "The river Kishon swept them away, that ancient river" (Judg. 5:21 ). (The earth) continued, saying to Him: Give me the oath by Thy right hand, that Thou wilt not claim them at my hand. The Holy One, blessed be He, put forth His right hand, and swore to the earth that He would not claim them, as it is said, "Thou stretchedst out thy right hand, the earth swallowed them" (Ex. 15:12). All the kings of the earth heard of the departure from Egypt, and the dividing of the Reed Sea; they trembled and feared, and fled from their place, as it is said, "The peoples have heard, they tremble" (Ex. 15:14).
