2 Samuel 6:11

‘ And the ark of YHWH remained in the house of Obed-edom the Gittite three months, and YHWH blessed Obed-edom, and all his house.'

The Ark of YHWH remained where it had been placed in the house of Obed-edom the Gittite for three months, and the consequence was that Obed-edom and the whole of his house enjoyed special blessing. We are not told the form that the blessing took. They may have experienced a greater than usual sense of great joy and worship because of a sense of the presence of YHWH, or their harvests may have been unusually fruitful. Whatever it was, however, it was something that was apparent, even to outsiders.
