What is the meaning of Mark 4:17?

* The two F.O.G. Bibles & Commentary below are currently a work in progress.

But they themselves have no root, and they remain for only a season. When trouble or persecution comes because of the word, they quickly fall away.

Berean Standard Bible (BSB)

They have no root in themselves, but are short-lived. When oppression or persecution arises because of the word, immediately they stumble.
