تَعِبَ الْعَامِلُ. غَابَ صَدِيقُهُ.
The worker became tired. His friend was absent.
The wording alone does not establish a causal relationship. These may be independent facts. If external context shows that the friend's absence added to the worker's duties, then a causal or explanatory reading becomes possible.
Rhetorical criticism must not present a possible interpretation as a necessary implication. The strength of the conclusion should track the strength of the contextual evidence.
