«الَّذِينَ يَنْقُضُونَ عَهْدَ اللَّهِ»
Those who break God’s covenant.
«نقض» has a familiar sense of untying or undoing something bound or constructed. A covenant is conceptualized as a binding or knot, and “undoing” is transferred to violating it.
No further feature of the binding or the covenant is developed to reinforce one side. This makes it an unqualified metaphor; mention of the covenant supplies the intended object and contextual evidence.
