¹ tn Heb “discerning mind.” The term לֵב (lev, “mind, heart”) is a synecdoche of part (= heart/mind) for the whole (= person); cf. TEV, NLT “intelligent people.” Placing “heart” and “ear” in parallel encompasses more of the process of acquiring knowledge. The ear listens for and to instruction, and the mind considers what is heard to acquire knowledge.

¹ tn The word מְזִמָּה (m^ezimmah, “discretion”) is the ability to know the best course of action for achieving one’s goal. It is knowledge and understanding with a purpose. This kind of knowledge enables one to make the right choices that will protect him from blunders and their consequences (cf. NLT “wise planning”; CEV “sound judgment”).

² tn As a stative verb יָדַע (yadaʿ) can mean “to know” or, as here, “to come to know,” or “to become wise in” (BDB 394). This term refers to experiential knowledge, not just cognitive knowledge; it includes the intellectual assimilation and practical use of what is acquired.

³ tn Heb “knowledge of the Holy One” (so ASV, NAB, NASB, NIV, NRSV). Knowledge of God implies an understanding of his character and ways and acknowledging or adopting his values. The noun דַּעַת (daʿat), traditionally taken as “knowledge” from the root יָדַע (yadaʿ, “to know”), may also be related to the root דָּעָה (daʿah, “to seek, request,” see NIDOTTE 959, s.v.). The homonym of דַּעַת (daʿat) is not widely recognized, but the meaning of seeking or having concern for God (and his ways) would fit the context well. Cf. Hos 6:3 for an example of the verb דָּעָה.

¹ tn The term “knowledge” (γνῶσις, gnōsis) used here is not the same as is found in 2 Pet 1:2, 3, 8; 2:20. This term is found in 1:5 and 1:6.

⁶ tn Grk “the [rich] knowledge of our Lord Jesus Christ.” Verse 8 in Greek does not make a full stop (period), for v. 9 begins with a subordinate relative pronoun. Contemporary English convention requires a full stop in translation, however.

³ tn The word ἐπίγνωσις (epignōsis) could simply mean knowledge, but J. B. Mayor (Jude and Second Peter, 171-74) has suggested that it is often a fuller knowledge, especially in reference to things pertaining to spiritual truth. R. Bauckham (Jude, 2 Peter [WBC], 169-70) argues that it refers to the knowledge of God that is borne of conversion, but this is probably saying too much and is asking questions of the author that are foreign to his way of thinking. The term is used in 1:2, 3, 8; 2:20 (the verb form occurs twice, both in 2:21). In every instance it evidently involves being in the inner circle of those who connect to God, though it does not necessarily imply such a direct and relational knowledge of God for each individual within that circle. An analogy would be Judas Iscariot: Even though he was a disciple of the Lord, he was not converted.

¹ tn Grk “living together according to knowledge, as to the weaker, female vessel.” The primary verbal ideas of v. 7 are contained in participles (“living together…showing honor”) but they continue the sense of command from the previous paragraphs.

² sn Speech and knowledge refer to the spiritual gifts God had blessed them with (as v. 7 confirms). Paul will discuss certain abuses of their gifts in chapters 12-14, but he thanks God for their giftedness.

² sn The “prophecy” about the ship serves to underscore Paul’s credibility as an agent of God. Paul addressed his audience carefully and drew attention to the sovereign knowledge of God.

¹ sn Jesus could see. Supernatural knowledge of what the disciples were thinking is not necessarily in view here. Given the disciples’ confused statements in the preceding verses, it was probably obvious to Jesus that they wanted to ask what he meant.

³ tn Heb “understanding riddles.” Possible meanings include “double-dealing” (BDB 295 s.v. חִידָה; cf. TEV, CEV) and “with a good knowledge of intrigue” (HALOT 309 s.v. חִידָה; cf. NAB, NASB, NIV, NRSV, NLT).

¹ tn The form is an active participle, יֹדֵעַ (yodeaʿ); it describes the righteous as “knowing, caring for, having sympathetic knowledge for, or considering favorably” the legal needs of the poor. Cf. NAB “has a care for”; NASB “is concerned for.”

¹ tn The text uses “man” as the subject and the active participle תּוֹעֶה (toʿeh) as the predicate. The image of “wandering off the path” signifies leaving a life of knowledge, prudence, and discipline.

³ sn This line features a mixed metaphor: The “ear” is pictured “seeking.” The wise person is listening for (on the lookout for) things worth listening to in the pursuit of knowledge.

² sn The term כֹּסֶה (koseh, “covers; hides”) does not mean that he never shares his knowledge, but discerns when it is and is not appropriate to speak, cf. 10:14; 17:27.

³ tn In what sense the fool “dies” is unclear. Fools ruin their lives and the lives of others by their lack of discipline and knowledge. The contrast is between enhancing life and ruining life.

² tn The noun is “shrewdness,” i.e., the right use of knowledge in special cases (see also the discussion in 1:4); cf. NLT “good judgment.” The word in this sentence is an adverbial accusative of specification.

¹ sn This statement does not imply there was a vision. He is simply saying that this experience of God was real and personal. In the past his knowledge of God was what he had heard—hearsay. This was real.

¹ sn Eliphaz is giving to Job the thoughts and words of the pagans, for they say, “How does God know, and is there knowledge in the Most High?” (see Pss 73:11; 94:11).
