She Did Not Return - Genesis 8:8-12

Genesis 8:8-12 ESV 

Then he sent forth a dove from him, to see if the waters had subsided from the face of the ground.

But the dove found no place to set her foot, and she returned to him to the ark, for the waters were still on the face of the whole earth. So he put out his hand and took her and brought her into the ark with him.

He waited another seven days, and again he sent forth the dove out of the ark.

And the dove came back to him in the evening, and behold, in her mouth was a freshly plucked olive leaf. So Noah knew that the waters had subsided from the earth.

Then he waited another seven days and sent forth the dove, and she did not return to him anymore.

Now a dove is released. Unlike the raven, it finds no resting place until the third time. The first time might correlate to the time before Israel when the dove finds no where to land. The waters provide no resting place. 

The second time it returns with a plucked olive leaf. The olive tree is symbolic of Israel. The Spirit of God chooses a people to bring the light into the world. 

The third time the dove is released and does not return. This might correspond to the giving of the Holy Spirit into the body of Christ and made available to rest of the world.
