The Parable Of The Owner Of The House

Matthew 13:52:

⁵² He said to them, “Therefore every teacher of the law who has become a disciple in the kingdom of heaven is like the owner of a house who brings out of his storeroom new treasures as well as old.”

The word treasure in verse 52 means something slightly different than it does in verse 44 in the Parable of the Hidden Treasure, where it implies gems and other precious things. In verse 52, it means a place for treasure, not the treasure itself. In other words, Jesus refers to "a treasure house," "a treasury," "a storehouse," or "a storeroom" where a person would keep necessary items like food, clothing, supplies, and family valuables for safekeeping. In context, then, the minister is to use what he has learned and experienced for the benefit of his spiritual family—he is to use as resources all the things he has stored away from his study of God's truth and his know-how in living God's way to lead and provide for his flock.
The "new and old" refers to food stored in a storeroom. The master of the house is in charge of ensuring that his storeroom contains everything needed to feed his family. A prudent householder balances serving his oldest store with the new. In this sense, seeing the value in the old, he wisely serves his family old store as well as the fresh "off-the-vine" food, mixing them in balance so that neither is wasted.

Jesus wants His ministers to teach their spiritual families by carefully balancing the teaching of the Old and the New Testaments (Matthew 5:17-19; Acts 26:22-23). It does not mean that the old is thrown away or is wrong. In the parables, Jesus did a similar thing by taking the old understanding of God's Kingdom and focusing new light on it to expand the people's understanding of its character and future course.

Ministers of Christ may not grasp and understand all the wisdom of God, but having received His instruction and sufficiently understood His message, they are commissioned to make use of this spiritually rich treasure to enrich others (Galatians 6:10). Taught by Jesus Christ and inspired in understanding His Word, ministers are to reflect that knowledge to their spiritual families, their fellow members of the church.
