Mark 4 – The seed that was sown on the good soil (those chosen of the Father) bear fruit.

Mark 4:20
"And those are the ones on whom seed was sown on the good soil; and they hear the word and accept it, and bear fruit, thirty, sixty, and a hundredfold."
The seed that was sown on the good soil (those chosen of the Father) bear fruit. The seed bears good works in those who are chosen to be His. Those good works are fruits. The numbers used by Yeshua are very interesting: a hundred, sixty, and thirty. The Greek term used for "hundredfold" actually means a "hundred." This should actually read "And those are the ones on whom seed was sown on the good soil; and they hear the word and accept it, and bear fruit, thirty, sixty, and a hundredfold." It probably is a reference to the age they will start bearing good fruit. We are told that Abraham bore Isaac at the age of 100.

Gen. 21:5 Now Abraham was one hundred years old when his son Isaac was born to him.

Isaac bore Jacob at age 60.

Gen. 25:26 And afterward his brother came forth with his hand holding on to Esau’s heel, so his name was called Jacob; and Isaac was sixty years old when she gave birth to them.

While we may think that Jacob bore Rueben (or Joseph) at age 30, but that is not the case. The age of Jacob is not given at that time, but it appears that he was much older than 30. He was probably between the ages of 74 and 91. The significance of bearing fruit at age 30 is likely referring to the age of the service of a Levite.

Num. 4:2-3 “Take a census of the descendants of Kohath from among the sons of Levi, by their families, by their fathers’ households, 3from thirty years and upward, even to fifty years old, all who enter the service to do the work in the tent of meeting.

Or Yeshua could be referring to Himself.

Luke 3:23 And when He began His ministry, Jesus Himself was about thirty years of age, being supposedly the son of Joseph, the son of Eli,
