## the devil comes and takes away the word from their heart ##
This means that he causes them to forget the word of God that they have heard.
## takes away ##
In the parable this was a metaphor of a bird snatching away the seeds. Try to use words in your language that keep that image. (See: [[rc://en/ta/man/translate/figs-metaphor]])
This can be translated with an active verb: "so they might not believe with the result that God saves them." Since this is the devil's purpose, it can be translated as "because the devil thinks, 'They must not believe and they must not be saved.'" (See: [[rc://en/ta/man/translate/figs-activepassive]])
