2 John 1:5

5 and now I beseech thee, Kyria, not as writing to thee a new command, but which we had from the beginning, that we may love one another,

2 John 1:5 Meaning and Commentary

2 John 1:5

And now I beseech thee, lady
Or "Kyria", which word the Syriac and Arabic versions retain, as if it was a proper name: the apostle having finished the inscription, salutation, and congratulation in the preceding verses, passes to an exhortation and entreaty to observe the commandment of love to one another, which is not a new commandment, but what was from the beginning:

not as though I wrote a new commandment (See Gill on 1 John 2:7) and (See Gill on 1 John 2:8).

2 John 1:5 In-Context

3 there shall be with you grace, kindness, peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love.
4 I rejoiced exceedingly that I have found of thy children walking in truth, even as a command we did receive from the Father;
5 and now I beseech thee, Kyria, not as writing to thee a new command, but which we had from the beginning, that we may love one another,
6 and this is the love, that we may walk according to His commands; this is the command, even as ye did hear from the beginning, that in it ye may walk,
7 because many leading astray did enter into the world, who are not confessing Jesus Christ coming in flesh; this one is he who is leading astray, and the antichrist.
