Genesis 8:12
He waited seven more days and sent the dove out again, but this time it did not return to him.
Qumran 4Q252, fr. I (Gen. vi, 3—XV, 17)
[this is the twenty-]fourth [day] of the eleventh month, the first day of the wee[k. And Noah knew that the waters had subsided] from the earth (viii, II).
Qumran 4Q252, fr. I (Gen. vi, 3—XV, 17)
At the end of another [seven days(?), he sent forth the dove and it did not] return again (viii, 12)—this is the f[irst] day [of the twelfth] month, [the first day] of the week. At the end of three [weeks after Noah had sent forth the dov]e which did not return to him any more, the wa[ters] dried up [from the earth and] Noah removed the covering of the ark and looked, and behold, the face of the ground was dry (viii, 13)
(Genesis 8:12 mentions the dove not returning one week earlier: “12He waited seven more days and sent the dove out again, but this time it did not return to him.“)
