Romans 15:28

28.And sealed to them this fruit, etc. I disapprove not of what some think, that there is here an allusion to a practice among the ancients, who closed up with their seals what they intended to lay up in safety. Thus Paul commends his own faithfulness and integrity; as though he had said, that he was an honest keeper of the money deposited in his hands, no otherwise than if he carried it sealed up. (462) — The word fruit seems to designate the produce, which he had before said returned to the Jews from the propagation of the gospel, in a way similar to the land, which by bringing forth fruit supports its cultivator.
