"Do not forsake the gathering of yourselves together" they say means God wants you at every meeting.

It begins at Hebrew 10:22 "we should approach" meaning together as a believing body spiritually approach the high priest (entering the holy by the blood of Iesou). So then later the writer would not switch to writing about the good habit of gathering together.
It coincides with 1 Corinthians 12:21 The eye cannot say to the hand, "I don't need you!" And the head cannot say to the feet, "I don't need you!"
Do not forsake any part of the Body that appears in Revelation 14:1, I'm sure that is what it means. To be sure Hebrews 10:25 has a spiritual meaning.
