My brethren, when you come together to eat, be waiting for one another.
I Corinthians 11:33

Let us hold fast the confession of our hope without wavering, for He who promised is faithful; and let us consider how to stimulate one another to love and ideal acts, not forsaking our own assembling together [of brethren; GREEK: συναγωγην, gathering those dispersed/scattered], according as the practice [by neglect] of some is, but [rather] encouraging one another, and so much the more as you observe the day drawing near.
Hebrews 10:23-25

Do your diligence therefore to meet together more frequently for thanksgiving to God and for His glory. For when you meet together frequently, the powers of Satan are cast down; and his mischief comes to nought in the concord of your faith.
I Ignatius to the Ephesians 13:1

But assemble yourselves all together with undivided heart.
Ignatius to the Philadelphians 6:2
