2 John 1:1; 2 John 1:5; 2 John 1:8

1 The elder unto the elect lady and her children, whom I love in the truth; and not I only, but also all they that have known the truth;
5 And now I beseech thee, lady, not as though I wrote a new commandment unto thee, but that which we had from the beginning, that we love one another.
8 Look to yourselves, that we lose not those things which we have wrought , but that we receive a full reward.
