Jesus begins to explain how some people are like the seeds that were sown in good soil. Alternate translation: "those people that were like seeds sown" (See: [[rc://en/ta/man/translate/figs-metaphor]])
This refers to the grain that the plants produce. Alternate translation: "some produce thirty grains, some produce sixty grains, and some produce a hundred grains" or "some produce 30 times the grain that was sown, some produce 60 times the grain that was sown, and some produce 100 times the grain that was sown" (See: [[rc://en/ta/man/translate/figs-ellipsis]] or [[rc://en/ta/man/translate/translate-numbers]])
