In the Genesis flood narrative, Noah sent the dove out again after it returned to the Ark. Genesis 8 describes Noah first sending a raven, then sending a dove to learn whether the floodwaters had receded.
The dove initially returned because it found no place to rest. Noah waited seven days and sent it again; this time it returned with a freshly plucked olive leaf. After another seven days, Noah sent the dove a third time, and it did not return.
This sequence is distinct from the question of which bird Noah sent first. The raven and the dove serve different stages of the story, while the repeated seven-day intervals provide a structured pattern. The olive leaf is evidence that vegetation had become visible, not a statement that all the floodwaters had already disappeared.
