¹ tn The expression “the sweat of your brow” is a metonymy, the sweat being the result of painful toil in the fields.

² sn Until you return to the ground. The theme of humankind’s mortality is critical here in view of the temptation to be like God. Man will labor painfully to provide food, obviously not enjoying the bounty that creation promised. In place of the abundance of the orchard’s fruit trees, thorns and thistles will grow. Man will have to work the soil so that it will produce the grain to make bread. This will continue until he returns to the soil from which he was taken (recalling the creation in 2:7 with the wordplay on Adam and ground). In spite of the dreams of immortality and divinity, man is but dust (2:7), and will return to dust. So much for his pride.

³ sn In general, the themes of the curse oracles are important in the NT teaching that Jesus became the cursed one hanging on the tree. In his suffering and death, all the motifs are drawn together: the tree, the sweat, the thorns, and the dust of death (see Ps 22:15). Jesus experienced it all, to have victory over it through the resurrection.

⁴ tn The introduction of the conditional clause with an interrogative particle prods the answer from Cain, as if he should have known this. It is not a condemnation, but an encouragement to do what is right.

⁵ tn The Hebrew text is difficult, because only one word occurs, שְׂאֵת (sÿ’et), which appears to be the infinitive construct from the verb “to lift up” (נָאָשׂ, na’as). The sentence reads: “If you do well, uplifting.” On the surface it seems to be the opposite of the fallen face. Everything will be changed if he does well. God will show him favor, he will not be angry, and his face will reflect that. But more may be intended since the second half of the verse forms the contrast: “If you do not do well, sin is crouching….” Not doing well leads to sinful attack; doing well leads to victory and God’s blessing.

⁶ tn The Hebrew term translated “crouching” (רֹבֵץ, rovets) is an active participle. Sin is portrayed with animal imagery here as a beast crouching and ready to pounce (a figure of speech known as zoomorphism). An Akkadian cognate refers to a type of demon; in this case perhaps one could translate, “Sin is the demon at the door” (see E. A. Speiser, Genesis [AB], 29, 32-33).

⁷ tn Heb “and toward you [is] its desire, but you must rule over it.” As in Gen 3:16, the Hebrew noun “desire” refers to an urge to control or dominate. Here the desire is that which sin has for Cain, a desire to control for the sake of evil, but Cain must have mastery over it. The imperfect is understood as having an obligatory sense. Another option is to understand it as expressing potential (“you can have [or “are capable of having”] mastery over it.”). It will be a struggle, but sin can be defeated by righteousness. In addition to this connection to Gen 3, other linguistic and thematic links between chaps. 3 and 4 are discussed by A. J. Hauser, “Linguistic and Thematic Links Between Genesis 4:1-6 and Genesis 2–3,” JETS 23 (1980): 297-306.

⁸ tn The oath formula is used: “if you do us harm” means “so that you will not do.”

⁹ tn Heb “touched.”

¹⁰ tn Heb “and just as we have done only good with you.”

¹¹ tn Heb “and we sent you away.”

¹² tn The Philistine leaders are making an observation, not pronouncing a blessing, so the translation reads “you are blessed” rather than “may you be blessed” (cf. NAB).

¹³ tn Heb “Pharaoh will lift up your head.” This Hebrew idiom usually refers to restoring dignity, office, or power. It is comparable to the modern saying “someone can hold his head up high.”

¹⁴ tn Heb “according to the former custom.”
