'Fertile' in the Bible

Then He told them a parable, saying, “There was a rich man whose land was very fertile and productive.

And he said, Lord, let it be for this year, and I will have the earth turned up round it, and put animal waste on it, to make it fertile:

But if some of the branches were broken off, and you, an olive-tree of the fields, were put in among them, and were given a part with them in the root by which the olive-tree is made fertile,

For if you have these things in good measure, they will make you fertile and full of fruit in the knowledge of our Lord Jesus Christ.
