A.T. Robertson Commentary Acts 2:44

"And all that believed were together, and had all things common;" — Acts 2:44 (ASV)

Were together (ησαν επ το αυτο). Some MSS. ησαν κα (were and). But they were together in the same place as in 2:1.

And had (κα ειχον). Imperfect active, kept on having, a habit in the present emergency.

Common (κοινα). It was not actual communism, but they held all their property ready for use for the common good as it was needed (4:32). This situation appears nowhere else except in Jerusalem and was evidently due to special conditions there which did not survive permanently. Later Paul will take a special collection for the poor saints in Jerusalem.
