1 John, Chapter 3, verses 10-20
3 who therefore ought obediently to keep his commandments, 11 as also brotherly to love one anotherMark, Chapter 14, verses 10-42
10 Judas selleth his master for money, 12 Christ himself foretelleth how he shall be betrayed by one of his disciples; after the Passover prepared and eaten, instituteth his Supper, 26 declareth aforehand the flight of all his disciples and Peter's denial14
14:10 Judas went to the chief priests - Immediately after this reproof, having anger now added to his covetousness. Mat 26:14; Luk 22:3.
14:13 Go into the city, and there shall meet you a man - It was highly seasonable for our Lord to give them this additional proof both of his knowing all things, and of his influence over the minds of men.
14:15 Furnished - The word properly means, spread with carpets.
14:24 This is my blood of the New Testament - That is, this I appoint to be a perpetual sign and memorial of my blood, as shed for establishing the new covenant, that all who shall believe in me may receive all its gracious promises.
14:25 I will drink no more of the fruit of the vine, till I drink it new in the kingdom of God - That is, I shall drink no more before I die: the next wine I drink will not be earthly, but heavenly.
14:26 Mat 26:30; Luk 22:39; Joh 18:1.
14:27 This night - The Jews in reckoning their days began with the evening, according to the Mosaic computation, which called the evening and the morning the first day, Gen 1:5. And so that which after sunset is here called this night is, Mar 14:30, called to - day. The expression there is peculiarly significant.Verily I say to thee, that thou thyself, confident as thou art, to - day, even within four and twenty hours; yea, this night, or ever the sun be risen, nay, before the cock crow twice, before three in the morning, wilt deny me thrice. Our Lord doubtless spoke so determinately, as knowing a cock would crow once before the usual time of cock crowing. By Mar 13:35, it appears, that the third watch of the night, ending at three in the morning, was commonly styled the cock crowing. Zec 13:7.
14:32 Mat 26:36.
14:33 Sore amazed - The original word imports the most shocking amazement, mingled with grief: and that word in the next verse which we render sorrowful intimates, that he was surrounded with sorrow on every side, breaking in upon him with such violence, as was ready to separate his soul from his body.
14:36 Abba, Father - St. Mark seems to add the word Father, by way of explication.
14:37 Saith to Peter - The zealous, the confident Peter.

3:10 Neither he that loveth not his brother - Here is the transition from the general proposition to one particular.
3:12 Who was of the wicked one - Who showed he was a child of the devil by killing his brother. And wherefore slew he him - For any fault? No, but just the reverse; for his goodness.
3:13 Marvel not if the world hate you - For the same cause.
3:14 We know - As if he had said, We ourselves could not love our brethren, unless we were passed from spiritual death to life, that is, born of God. He that loveth not his brother abideth in death - That is, is not born of God. And he that is not born of God, cannot love his brother.
3:15 He, I say, abideth in spiritual death, is void of the life of God. For whosoever hateth his brother, and there is no medium between loving and hating him, is, in God's account, a murderer: every degree of hatred being a degree of the same temper which moved Cain to murder his brother. And no murderer hath eternal life abiding in him - But every loving believer hath.For love is the beginning of eternal life. It is the same, in substance, with glory.
3:16 The word God is not in the original. It was omitted by the apostle just as the particular name is omitted by Mary, when she says to the gardener, "Sir, if thou hast borne him hence;" and by the church, when she says, "Let him kiss me with the kisses of his mouth," Sol 1:2; in both which places there is a language, a very emphatical language, even in silence. It declares how totally the thoughts were possessed by the blessed and glorious subject. It expresses also the superlative dignity and amiableness of the person meant, as though He, and He alone, was, or deserved to be, both known and admired by all. Because he laid down his life - Not merely for sinners, but for us in particular. From this truth believed, from this blessing enjoyed, the love of our brethren takes its rise, which may very justly be admitted as an evidence that our faith is no delusion.
3:17 But whoso hath this world's good - Worldly substance, far less valuable than life. And seeth his brother have need - The very sight of want knocks at the door of the spectator's heart.And shutteth up - Whether asked or not. His bowels of compassion from him, how dwelleth the love of God in him - Certainly not at all, however he may talk, Jo1 3:18,of loving God.
3:18 Not in word - Only. But in deed - In action: not in tongue by empty professions, but in truth.
3:19 And hereby we know - We have a farther proof by this real, operative love. That we are of the truth - That we have true faith, that we are true children of God. And shall assure our hearts before him - Shall enjoy the assurance of his favour, and the "testimony of a good conscience toward God." The heart, in St. John's language, is the conscience. The word conscience is not found in his writings.
3:20 For if we have not this testimony, if in anything our heart, our own conscience, condemn us, much more does God, who is greater than our heart - An infinitely holier and a more impartial Judge. And knoweth all things - So that there is no hope of hiding it from him.
