In the context of a biblical reference, passive-aggressive behavior between a couple might manifest in subtle, indirect ways. For instance, during a disagreement, one partner could quote Matthew 7:3-5, insinuating that the other should first address their own flaws before pointing out theirs. The partner responding might then reference Proverbs 15:1, subtly suggesting that gentle words could diffuse tension and prevent further conflict. Through these biblical allusions, the couple subtly expresses their frustrations and uses religious texts to communicate their discontent, potentially revealing underlying issues.
