A.T. Robertson Commentary Mark 4:20

"And those are they that were sown upon the good ground; such as hear the word, and accept it, and bear fruit, thirtyfold, and sixtyfold, and a hundredfold." — Mark 4:20 (ASV)

Bear fruit (καρποφορουσιν). Same word in Mt 13:23 and Lu 8:15. Mark gives the order from thirty, sixty, to a hundred, while Mt 13:23 has it reversed.
