مِثْلُكَ لَا يَبْخَلُ
Someone like you is not miserly.
غَيْرُكَ لَا يَجُودُ
Someone other than you is not generous.
These expressions can serve as kināyah for a quality of the addressee. In the first, a phrase about a person ‘like you’ conveys an assessment of you; enumerating literally similar persons is not the point. In the second, denying generosity of ‘another’ can imply generosity of the addressee.
The fronting is not explained solely by a supposed grammatical necessity. The kināyah and the communicative purpose give the arrangement its rhetorical force.
