William Burkitt on Matthew 13:51

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.
