Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
Though who is Christ not ashamed to call brethren?
For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren
As it also it speaks of who is none of his also
Now if any man have not the Spirit of Christ he is none of his.
Says the Lord knoweth them that are his
Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his.
And, Let every one that nameth the name of Christ depart from iniquity.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Contrast the knowing part
The Lord knoweth them that are his.

And then will I profess unto them, I never knew you
And, Let every one that nameth the name of Christ depart from iniquity.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
So depart from iniquity
Let every one that nameth the name of Christ depart from iniquity.
Or depart from me ye that work iniquity
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Shown in this other way here (not the same) but as one belonging to Christ

Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink?
 
And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethrenye have done it unto me.
