Imamat 18:16

18:16 You must not have sexual intercourse with your brother’s wife; she is your brother’s nakedness. ¹ 

Matius 14:3-4

14:3 For Herod had arrested John, bound him, ²  and put him in prison on account of Herodias, his brother Philip’s wife, 14:4 because John had repeatedly told ³  him, “It is not lawful for you to have her.” ⁴ 

[18:16]  ¹ sn Regarding the last clause, see the notes on vv. 7 and 10 above.

[14:3]  ² tc ‡ Most witnesses (א² C D L W Z Θ 0106 Ë^1,13 33 Ï lat) read αὐτόν (auton, “him”) here as a way of clarifying the direct object; various important witnesses lack the word, however (א* B 700 pc ff¹ h q). The original wording most likely lacked it, but it has been included here due to English style. NA²⁷ includes the word in brackets, indicating reservations about its authenticity.

[14:4]  ³ tn The imperfect tense verb is here rendered with an iterative force.

[14:4]  ⁴ sn This marriage of Herod to his brother Philip’s wife was a violation of OT law (Lev 18:16; 20:21). In addition, both Herod Antipas and Herodias had each left marriages to enter into this union.
