Mark 6:18

6:18 For John had repeatedly told ¹  Herod, “It is not lawful for you to have your brother’s wife.” ² 

[6:18]  ¹ tn The imperfect tense verb is here rendered with an iterative force.

[6:18]  ² sn It is not lawful for you to have your brother’s wife. This 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.
