«وَصَيَّرْتُ وَعْظِي أُحْبُولَةً»
I made my preaching into a snare.
«أَرِيعُ الْقَنِيصَ بِهَا وَالْقَنِيصَةَ»
By this device I seek to capture prey.
Uḥbūlah means a snare or trap. The hook, prey and snare form a sustained field of imagery. His persuasive sermon is represented as a means of attracting attention and gifts.
The metaphor reveals character, not merely style. Words of moral correction are connected with practical personal benefit, which complicates how the audience understands the preacher.
