'Thirty fold' in the Bible

But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold.

And what was sown on the good ground, this is he that heareth the word, and understandeth it; who also beareth fruit, and yieldeth, one a hundred fold, another sixty, another thirty fold.

and other fell to the good ground, and was giving fruit, coming up and increasing, and it bare, one thirty-fold, and one sixty, and one an hundred.'

And these are they which are sown on good ground; such as hear the word, and receive it, and bring forth fruit, some thirtyfold, some sixty, and some an hundred.
