'Unproductive' in the Bible

The men of the city said to Elisha, "Please now, the location of the city [is] good, as my master can see, but the water [is] bad and the land unproductive."

And what was sown into the thorn plants--this is the one who hears the word, and the anxiety of this world and the deceitfulness of wealth choke the word and it becomes unproductive.

and the cares of the world and the deceitfulness of wealth and the desires for other [things] come in [and] choke the word and it becomes unproductive.

For if I pray in a tongue, my spirit prays but my mind is unproductive.

For [if] these [things] are yours and are increasing, this does not make [you] useless or unproductive in the knowledge of our Lord Jesus Christ.
