Answer:
There are other verses in the old Testament as well as the New, but the one verse that readily comes to mind is…
Hebrews 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
The early church was composed of small home groups, as it still is today in some countries where it is forbidden to go to “church”.
It is important we all have a time when we gather together and assemble ourselves with other Believers and corporately worship. It is also apparent that supporting the local church is also part of what pleases God and there are many verses which support this.
Hebrews 10:25 is definitely talking about getting together with other believers on a regular basis.
God Bless,
