Imamat 18:20

18:20 You must not have sexual intercourse ¹  with the wife of your fellow citizen to become unclean with her.

Imamat 19:18

19:18 You must not take vengeance or bear a grudge ²  against the children of your people, but you must love your neighbor as yourself. ³  I am the Lord.

[18:20]  ¹ tn Heb “And to the wife of your fellow citizen you shall not give your layer for seed.” The meaning of “your layer” (שְׁכָבְתְּךָ, shÿkhavtÿkha) is uncertain (see B. A. Levine, Leviticus [JPSTC], 122, “you shall not place your layer of semen”; but cf. also J. E. Hartley, Leviticus [WBC], 283, and the literature cited there for the rendering, “you shall not give your penis for seed”).

[19:18]  ² tn Heb “and you shall not retain [anger?].” This line seems to refer to the retaining or maintaining of some vengeful feelings toward someone. Compare the combination of the same terms for taking vengeance and maintaining wrath against enemies in Nahum 1:2 (see J. E. Hartley, Leviticus [WBC], 305).

[19:18]  ³ sn Some scholars make a distinction between the verb אָהַב (’ahav, “to love”) with the direct object and the more unusual construction with the preposition לְ (lamed) as it is here and in Lev 19:34 and 2 Chr 19:2 only. If there is a distinction, the construction here probably calls for direct and helpful action toward one’s neighbor (see the discussion in J. E. Hartley, Leviticus [WBC], 305, and esp. 317-18). Such love stands in contrast to taking vengeance or bearing a grudge against someone and, in NT terms, amounts to fulfilling the so-called “golden rule” (Matt 7:12).
