And he said to them, “Therefore every expert in the law who has been discipled about the Kingdom of Heaven is like a man who is a master of a house, who brings out of his treasure things new and old.” Bible see other translations

“has been discipled.” The Greek word mathēteuō (#3100 μαθητεύω) means to be a disciple, and the fact that it is an aorist participle means that the disciple has graduated and finished his training and reached a level of expertise. It is related to the noun mathētēs (#3101 μαθητής; pronounced ma-thay-'tase) “disciple.” Some versions have “has been instructed,” but the REV reads “has been discipled” to maintain consistency with the word “disciple.”

“new and old.” The person who has been well trained about the Kingdom of Heaven has wisdom and knowledge and applies it well. Some of it is old knowledge that has been around for many generations, and some of it is new knowledge that has recently been revealed.
