{They continued steadfastly} ((8873)an proskarturountes).
Periphrastic active imperfect of proskarture(935c) as in  Ac 1:14 
(same participle in verse  46 ). {Fellowship} (koin(936e)i(8369)). Old
word from koin(936e)os (partner, sharer in common interest) and
this from koinos what is common to all. This partnership
involves participation in, as the blood of Christ ( Php 2:1 ) or
co-operation in the work of the gospel ( Php 1:5 ) or
contribution for those in need ( 2Co 8:4  9:13 ). Hence there is
wide diversity of opinion concerning the precise meaning of
koin(936e)ia in this verse. It may refer to the distribution of
funds in verse  44  or to the oneness of spirit in the community
of believers or to the Lord's Supper (as in  1Co 10:16 ) in the
sense of communion or to the fellowship in the common meals or
agapae (love-feasts). {The breaking of bread} (	(8869) klasei tou
artou). The word klasis is an old word, but used only by Luke
in the N.T. ( Lu 24:35  Ac 2:42 ), though the verb kla(935c) occurs
in other parts of the N.T. as in verse  46 . The problem here is
whether Luke refers to the ordinary meal as in  Lu 24:35  or to
the Lord's Supper. The same verb kla(935c) is used of breaking bread
at the ordinary meal ( Lu 24:30 ) or the Lord's Supper ( Lu
22:19 ). It is generally supposed that the early disciples
attached so much significance to the breaking of bread at the
ordinary meals, more than our saying grace, that they followed
the meal with the Lord's Supper at first, a combination called
agapai or love-feasts. "There can be no doubt that the
Eucharist at this period was preceded uniformly by a common
repast, as was the case when the ordinance was instituted"
(Hackett). This led to some abuses as in  1Co 11:20 . Hence it is
possible that what is referred to here is the Lord's Supper
following the ordinary meal. "To simply explain 	(8869) klasei tou
artou as='The Holy Communion' is to pervert the plain meaning of
words, and to mar the picture of family life, which the text
places before us as the ideal of the early believers" (Page). But
in  Ac 20:7  they seem to have come together especially for the
observance of the Lord's Supper. Perhaps there is no way to
settle the point conclusively here. {The prayers} (	ais
proseuchais). Services where they prayed as in  1:14 , in the
temple ( Ac 3:1 ), in their homes ( 4:23 ).
