Deuteronomy 17:17

17:17 Furthermore, he must not marry many ¹  wives lest his affections turn aside, and he must not accumulate much silver and gold.

Deuteronomy 21:15

Laws Concerning Children

21:15 Suppose a man has two wives, one whom he loves more than the other, ²  and they both ³  bear him sons, with the firstborn being the child of the less loved wife.

[17:17]  ¹ tn Heb “must not multiply” (cf. KJV, NASB); NLT “must not take many.”

[21:15]  ² tn Heb “one whom he loves and one whom he hates.” For the idea of שָׂנֵא (sane’, “hate”) meaning to be rejected or loved less (cf. NRSV “disliked”), see Gen 29:31, 33; Mal 1:2-3. Cf. A. Konkel, NIDOTTE 3:1256-60.

[21:15]  ³ tn Heb “both the one whom he loves and the one whom he hates.” On the meaning of the phrase “one whom he loves and one whom he hates” see the note on the word “other” earlier in this verse. The translation has been simplified for stylistic reasons, to avoid redundancy.
