1 tn Heb “Man, man shall not draw near to any flesh (שְׁאֵר, shÿ’er) of his body/flesh (בָּשָׂר, basar).” The repetition of the word “man” is distributive, meaning “any (or “every”) man” (GKC 395-96 §123.c; cf. Lev 15:2). The two words for “flesh” are combined to refer to emphasize the physical familial relatedness (see J. E. Hartley, Leviticus [WBC], 282, and B. A. Levine, Leviticus [JPSTC], 119).
2 tn Heb “to uncover [her] nakedness” (cf. KJV, ASV, NASB, NRSV), which is clearly euphemistic for sexual intercourse (see J. E. Hartley, Leviticus [WBC], 282, and B. A. Levine, Leviticus [JPSTC], 119). This expression occurs a number of times in the following context and is generally translated “have sexual intercourse with [someone],” although in the case of the father mentioned in the following verse the expression may be connected to the shame or disgrace that would belong to the father whose wife’s sexuality is violated by his son. See the note on the word “mother” in v. 7.
3 sn The general statement prohibiting sexual intercourse between close relatives serves as an opening summary statement for the following section, which gives details concerning which degrees of relationship are specifically forbidden.
4 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”).
