John Gill Bible Commentary

And his concubine played the whore against him,.... Was unfaithful to him and his bed, and broke the covenant and agreement between them; or "with him" (i), while she was with him in the house; or "before him" (k), of which he had knowledge and proof; though some think this is not to be understood of whoredom or adultery, but of her ill usage of him, and departure from him. The Targum is, she despised him; so Kimchi and Ben Gersom interpret it of her declining and turning aside from him, and returning to her father's house, as follows: and indeed, had she been guilty of such a crime, one would think he would never have sought after her to reconcile her, and take her again, since she not only deserved to be put away, but to be put to death according to the law of God: and went away from him to her father's house to Bethlehemjudah; where she was received, as she knew she should, having a parent perhaps too indulgent, and which was an encouragement to her to leave her husband: and was there some whole months or a year and four whole months, according to Ben Gersom; so Kimchi and Ben Melech observe the copulative "and" is wanting, which is expressed in Sa1 27:7 and "yamim, days", is so the times used for a year, Jdg 14:8. (i) "apud eum", Pagninus, Piscator; "cum eo", Junius & Tremellius. (k) "Conspectu ejus", Vatablus; "coram eo", Drusius.
