'Abated' in the Bible

And the waters returned from off the earth continually: and after the end of the hundred and fifty days the waters were abated.

Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;

And the dove came in to him in the evening; and, lo, in her mouth was an olive leaf pluckt off: so Noah knew that the waters were abated from off the earth.
