'Assembly' in the Bible

And himself is the head of the body -- the assembly -- who is a beginning, a first-born out of the dead, that he might become in all things -- himself -- first,

I now rejoice in my sufferings for you, and do fill up the things lacking of the tribulations of the Christ in my flesh for his body, which is the assembly,

salute ye those in Laodicea -- brethren, and Nymphas, and the assembly in his house;

and when the epistle may be read with you, cause that also in the assembly of the Laodiceans it may be read, and the epistle from Laodicea that ye also may read;
