Gevurot Meyruach Hakodesh 2:44-46

And all the [Jewish] Ma'aminim HaMeshichiyim were together and they were having all things in common. And they were selling their properties and possessions and were distributing tzedakah to everyone as someone had need. And yom yom, devoting themselves with one mind in the courts of the Beis Hamikdash, and from bais to bais, offering the Betzi'at HaLechem, they were together at tish with single-hearted exultation and hitlahavut.
