Instructions of Shuruppak

Ubara-Tutu is recorded in most copies of the Sumerian King List as being the final king of Sumer prior to the deluge. Ubara-tutu is briefly mentioned in tablet XI of the Epic of Gilgamesh, where he is identified as the father of Utnapishtim, a character who is instructed by the god Ea to build a boat in order to survive the coming flood.

  
Utnapishtim (Akkadian: 𒌓𒍣, "he has found life") was a legendary king of the ancient city of Shuruppak in southern Iraq, who, according to the Gilgamesh flood myth, one of several similar narratives, survived the Flood by making and occupying a boat. He is called by different names in different traditions: Ziusudra ("Life of long days", rendered Xisuthros, Ξίσουθρος in Berossus) in the earliest, Sumerian versions, later Shuruppak (after his city), Atra-hasis ("exceeding wise") in the earliest Akkadian sources, and Uta-napishtim ("he has found life") in later Akkadian sources such as the Epic of Gilgamesh.His father was the king Ubar-Tutu ("Friend of the god Tutu").

Uta-napishtim is the eighth of the antediluvian kings in Mesopotamian legend, just as Noah is the eighth from Enoch in Genesis. He would have lived around 2900 BC, corresponding to the flood deposit at Shuruppak between the Jemdet Nasr and Early Dynastic levels. In Mesopotamian narratives he is the Flood Hero, tasked by the god Enki (Akkadian Ea) to create a giant ship to be called Preserver of Life in preparation for a giant flood that will wipe out all life. The character appears in Tablet XI of the Standard Babylonian Epic of Gilgamesh, at the culmination of Gilgamesh's search for immortality. The story of Uta-napishtim has drawn scholarly comparisons due to the similarities between it and the storylines about Noah in the Bible.

Instructions of Shuruppak -  the Instructions date to the early third millennium BCE, being among the oldest surviving literature. 

"In those days, in those far remote times, in those nights, in those faraway nights, in those years, in those far remote years." 

These are the (Instructions) Mitzvot? given by Curuppag, the son of Ubara-Tutu.
