51 Jesus saith unto them, Have ye understood all these things? They say unto him, Yea, Lord. 52 Then said he unto them, Therefore every scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old. (Matthew 13:51-52 KJV)
William Burkitt’s Commentary
Observe here, 1. The title which our Saviour puts upon gospel-ministers; they are household stewards.
2. He points out the office of those stewards; and that is, to provide for the household both with plenty and variety. He must bring forth out of his treasure in plenty; and things new and old for their variety.
There are two essential qualifications in a steward, faithfulness and prudence: he must be honest and faithful, in bringing out of his own treasure, not another’s; and he must be prudent, in bringing things new, as well as old; not new truths, but old truths in as new dress: lest the household, by always feeding upon the same dish, do nauseate it, instead of being nourished by it.
