¹ tn Once more there is the familiar difficulty of determining whether the phrase refers (1) to what precedes or (2) to what follows. Here, because ἐν τούτῳ (en toutō) is followed by a clause introduced by ὅταν (hotan) which appears to be related, it is best to understand ἐν τούτῳ as referring to what follows. The following ὅταν clause is epexegetical to ἐν τούτῳ, explaining how we know that we love God’s children: “by this we know that we love God’s children, whenever we love God and keep his commandments.”

¹ tn Again whether the referent of the phrase ἐν τούτῳ (en toutō) (1) precedes or (2) follows is a problem. This time there are two ὅτι (hoti) clauses which follow. The first is an indirect discourse clause related to γινώσκομεν (ginōskomen) and giving the content of what believers know: “that we reside in him and he in us.” The second ὅτι clause is epexegetical (or explanatory) to the ἐν τούτῳ phrase, explaining how believers know that they reside in God and God remains in them: “in that he has given us of his Spirit.”

¹ sn Now. The author, after discussing three claims of the opponents in 1:6, 8, and 10 and putting forward three counterclaims of his own in 1:7; 1:9, and 2:1, now returns to the theme of “God as light” introduced in 1:5. The author will now discuss how a Christian may have assurance that he or she has come to know the God who is light, again by contrast with the opponents who make the same profession of knowing God, but lack the reality of such knowledge, as their behavior makes clear.

¹ tn Grk “knowing this [to be] foremost.” Τοῦτο πρῶτον (touto prōton) constitute the object and complement of γινώσκοντες (ginōskontes). The participle is loosely dependent on the infinitive in v. 2 (“[I want you] to recall”), perhaps in a telic sense (thus, “[I want you] to recall…[and especially] to understand this as foremost”). The following statement then would constitute the main predictions with which the author was presently concerned. An alternative is to take it imperativally: “Above all, know this.” In this instance, however, there is little semantic difference (since a telic participle and imperatival participle end up urging an action). Cf. also 2 Pet 1:20.

⁵ tc The Western ms D adds here a full saying that reads, “On the same day, as he saw someone working on the Sabbath he said, ‘Man, if you know what you are doing, you are blessed, but if you do not know, you are cursed and a violator of the law.’” Though this is not well enough attested to be considered authentic, many commentators have debated whether this saying might go back to Jesus. Most reject it, though it does have wording that looks like Rom 2:25, 27 and Jas 2:11.

⁵ tn Or “do not acknowledge me”; Heb “do not know me.” But “knowing” in Hebrew thought often involves more than intellectual knowledge; it involves emotional and volitional commitment as well. For יָדַע (yadaʿ) meaning “acknowledge” see 1 Chr 28:9; Isa 29:21; Hos 2:20; Prov 3:6. This word is also found in ancient Near Eastern treaty contexts where it has the idea of a vassal king acknowledging the sovereignty of a greater king (cf. H. Huffmon, “The Treaty Background of Hebrew yada,” BASOR 181 [1966]: 31-37).

² tc Heb “to know [?] the weary with a word.” Comparing it with Arabic and Aramaic cognates yields the meaning of “help, sustain.” Nevertheless, the meaning of עוּת (ʿut) is uncertain. The word occurs only here in the OT (see BDB 736 s.v.). Various scholars have suggested an emendation to עָנוֹת (ʿanot) from עָנָה (ʿanah, “answer”): “so that I know how to respond kindly to the weary.” Since the Qumran scroll 1QIsa^a and the Vulgate support the MT reading, that reading is retained.

² tc Heb “Surely [in] vain they strive, he accumulates and does not know who gathers them.” The MT as it stands is syntactically awkward. The verb forms switch from singular (“walks about”) to plural (“they strive”) and then back to singular (“accumulates and does not know”), even though the subject (generic “man”) remains the same. Furthermore there is no object for the verb “accumulates” and no plural antecedent for the plural pronoun (“them”) attached to “gathers.” These problems can be removed if one emends the text from הֶבֶל יֶהֱמָיוּן (hevel yehemayun, “[in] vain they strive”) to הֶבְלֵי הָמוֹן (hevle hamon, “vain things of wealth”). The present translation follows this emendation.

¹ tn Heb “[it] restores life.” Elsewhere the Hiphil of שׁוּב (shuv, “return”) when used with נֶפֶשׁ (nefesh, “life”) as object, means to “rescue or preserve one’s life” (Job 33:30; Ps 35:17) or to “revive one’s strength” (emotionally or physically; cf. Ruth 4:15; Lam 1:11, 16, 19). Here the point seems to be that the law preserves the life of the one who studies it by making known God’s will. Those who know God’s will know how to please him and can avoid offending him. See v. 11a.

³ tn The word פַּשׁ (pash) is a hapax legomenon. K&D 12:275 derived it from an Arabic word meaning “belch,” leading to the idea of “overflow.” BDB 832 s.v. defines it as “folly.” Several define it as “transgression” on the basis of the versions (Theodotion, Symmachus, Vulgate). The RSV took it as “greatly heed,” but that is not exactly “greatly know,” when the text beyond that requires “not know at all.” The NIV has “he does not take the least notice of wickedness.”

¹ tn The word, although difficult in its form, is “vanity,” i.e., that which is worthless. E. Dhorme (Job, 224) thinks that the form שָׁוְא (shavʾ) conceals the word שִׁיאוֹ (shiʾo, “his stature”). But Dhorme reworks most of the verse. He changes נִתְעָה (nitʿah, “deceived”) to נֵדַע (nedaʿ, “we know”) to arrive at “we know that it is vanity.” The last two words of the verse are then moved to the next. The LXX has “let him not think that he shall endure, for his end shall be vanity.”

² tn This line is fraught with difficulties (perceived or real), which prompt numerous suggestions. The reading of the MT is “he knows that a day of darkness is fixed in his hand,” i.e., is certain. Many commentators move “day of darkness” to the next verse, following the LXX. Then, suggestions have been offered for נָכוֹן (nakhon, “ready”), such as נֵכֶר (nekher, “disaster”); and for בְּיָדוֹ (b^eyado, “in his hand”) a number of ideas—לְאֵיד (l^eʾed, “calamity”) or פִּידוֹ (pido, “his disaster”). Wright takes this last view and renders it “he knows that misfortune is imminent,” leaving the “day of darkness” to the next verse.

² sn Do not know good from bad. This is a figure of speech called a merism (suggesting a whole by referring to its extreme opposites). Other examples are the tree of “the knowledge of good and evil” (Gen 2:9), the boy who knows enough “to reject the wrong and choose the right” (Isa 7:16; 8:4), and those who “cannot tell their right hand from their left” (Jonah 4:11). A young child is characterized by lack of knowledge.

⁴ sn The phrase the earth and the heaven fled from his presence can be understood (1) as visual imagery representing the fear of corruptible matter in the presence of God, but (2) it can also be understood more literally as the dissolution of the universe as we know it in preparation for the appearance of the new heaven and new earth (Rev 21:1).

⁵ tn Or “on.” The preposition ἐπί (epi) with the accusative case could mean “on, at, by, near”; given the nature of this scene appearing in a vision, it is difficult to know precisely which the author of Revelation intended. See BDAG 363 s.v. ἐπί 1.c.γ, “At, by, near someone or someth.”

³ tn The phrase “In fact” is supplied in the translation to bring out the ascensive quality of the clause. It would also be possible to supply here an understood repetition of the phrase “I know” from the beginning of the verse (so NRSV). Grk “and your last deeds [that are] greater than the first.”

¹ tn Because of the length and complexity of this Greek sentence, a new sentence was started here in the translation by supplying the phrase “I am also aware” to link this English sentence back to “I know” at the beginning of v. 2.

⁵ sn In 4:20 the author again describes the opponents, who claim to love God. Their failure to show love for their fellow Christians proves their claim to know God to be false: The one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.

¹ sn By this we know. According to the author of 1 John, the Father’s giving of the indwelling Holy Spirit to the believer is one means of providing assurance to the believer of his relationship to God. This is what was also stated in 1 John 3:24b in essentially identical terms.

¹ tn This ὅτι (hoti) is causal, giving the reason why the readers, as believers, ought to love one another: because love comes from God. The next clause, introduced by καί (kai), does not give a second reason (i.e., is not related to the ὅτι clause), but introduces a second and additional thought: Everyone who loves is fathered by God and knows God.
