SEV Biblia, Chapter 2:9
El que dice que est en la luz; y aborrece a su Hermano, el tal an est en tinieblas.
Clarke's Bible Commentary - 1 John 2:9
Verse 9. He that saith he is in the light] He that professes to be a convert to Christianity, even in the lowest degree; and hateth his brother - not only does not love him, but wills and does him evil, as the Jews did the Gentiles; is in darkness - has received no saving knowledge of the truth; and, whatever he may pretend, is in heathen ignorance, or even worse than heathen ignorance, to the present time, notwithstanding the clear shining of the light of the Gospel.
John Gill's Bible Commentary
Ver. 9. He that saith he is in the light , &c.] Is in Christ the light, or has the true knowledge of the light of the Gospel, or is illuminated by the Spirit of God; for persons may profess to be enlightened ones, and not be so: wherefore the apostle does not say, he that is in the light, but he that says he is, and hateth his brother ; who is so either by creation, as all men are brethren, having one Father, that has made them, and brought them up; or by regeneration, being born of God the Father, and in the same family and household of faith; and so regards such who are in a spiritual relation, whom to hate internally, or not to love, is inconsistent with being in the light, or having faith, which is always naturally and necessarily accompanied with the heat of love; for as light and heat, so faith and love go together: wherefore, let a man's profession of light be what it will, if love to his brother is wanting, he is in darkness even until now ; he is in a state of nature and unregeneracy, which is a state of darkness and ignorance; he is under the power of darkness, and in the kingdom of Satan; who is the ruler of the darkness of this world; he ever was so from his birth; he never was called nor delivered out of it, but is still in it to this moment, and so remains. This seems to be very much levelled against the Jews, who make hatred of the brother in some cases lawful: for they say f28 , if one man observes sin in another, and reproves him for it, and he does not receive his reproof, wtwanl rtwm , it is lawful to hate him; (see Gill on Matthew 5:43).
Matthew Henry Commentary
Verses 3-11 - What knowledge of Christ can that be, which sees not that he is mos worthy of our entire obedience? And a disobedient life shows there is neither religion nor honesty in the professor. The love of God is perfected in him that keeps his commandments. God's grace in his attains its true mark, and produces its sovereign effect as far as ma be in this world, and this is man's regeneration; though neve absolutely perfect here. Yet this observing Christ's commands, ha holiness and excellency which, if universal, would make the eart resemble heaven itself. The command to love one another had been in force from the beginning of the world; but it might be called a ne command as given to Christians. It was new in them, as their situatio was new in respect of its motives, rules, and obligations. And thos who walk in hatred and enmity to believers, remain in a dark state Christian love teaches us to value our brother's soul, and to drea every thing hurtful to his purity and peace. Where spiritual darknes dwells, in mind, the judgment, and the conscience will be darkened, an will mistake the way to heavenly life. These things demand seriou self-examination; and earnest prayer, that God would show us what we are, and whither we are going.

Vincent's NT Word Studies
9. Hateth (miswn). The sharp issue is maintained here as in Christ's words, "He that is not with me is against me" (Luke xi. 23). Men fall into two classes, those who are in fellowship with God, and therefore walk in light and love, and those who are not in fellowship with God, and therefore walk in darkness and hatred. "A direct opposition," says Bengel; where love is not, there is hatred. "The heart is not empty." See John iii. 20; vii. 7; xv. 18 sqq.; xvii. 14. The word hate is opposed both to the love of natural affection (filein), and to the more discriminating sentiment - love founded on a just estimate (agapan). For the former see John xii. 25; xv. 18, 19; compare Luke xiv. 26. For the latter, 1 John iii. 14, 15; iv. 20, Matt. v. 43; vi. 24; Eph. v. 28, 29. "In the former case, hatred, which may become a moral duty, involves the subjection of an instinct. In the latter case it expresses a general determination of character" (Westcott).
His brother (ton adelfon). His fellow-Christian. The singular, brother, is characteristic of this Epistle. See vv. 10, 11; iii. 10, 15, 17; iv. 20, 21; v. 16. Christians are called in the New Testament, Christians (Acts xi. 26; xxvi. 28; 1 Pet. iv. 16), mainly by those outside of the Christian circle. Disciples, applied to all followers of Christ (John ii. 11; vi. 61) and strictly to the twelve (John xiii. 5 sqq.). In Acts xix. 1, to those who had received only John's baptism. Not found in John's Epistles nor in Revelation. Brethren. The first title given to the body of believers after the Ascension (Acts i. 15, where the true reading is ajdelfwn brethren, for maqhtwn disciples). See Acts ix. 30; x. 23; xi. 29; 1 Thess. iv. 10; v. 26; 1 John iii. 14; 3 John 5, 10; John xxi. 23. Peter has hJ ajdelfothv the brotherhood (1 Peter ii. 17; v. 9). The believers. Under three forms: The believers (oiJ pistoi; Acts x. 45; 1 Tim. iv. 12); they that believe (oiJ pisteuontev; 1 Peter ii. 7; 1 Thess. i. 7; Eph. i. 19); they that believed (oiJ pisteusantev; Acts ii. 44; iv. 32; Heb. iv. 3). The saints (oi agioi); characteristic of Paul and Revelation. Four times in the Acts (ix. 13, 32, 41; xxvi. 10), and once in Jude (3). Also Heb. vi. 10; xiii. 24. In Paul, 1 Corinthians vi. 1; xiv. 33; Eph. i. 1, 15, etc. In Apoc. v. 8; viii. 3, 4; xi. 18, etc.
Until now (ewv arti). Though the light has been increasing, and though he may claim that he has been in the light from the first. The phrase occurs in John ii. 10; v. 17; xxvi. 24; and is used by Paul, 1 Cor. iv. 13; viii. 7; xxv. 6.
