A fainter, low-volume reuse, carried by recurrence or thematic coherence.
YHWH's word that 'goes out' from his mouth and does not return empty but accomplishes its purpose underlies the image of the word of the Lord sounding forth and bearing fruit everywhere. The 'going out' verb and effectual-word theology cohere, but the verbal contact is modest.
Low confidence'But God's word isn't chained' faintly echoes the promise that the word going out from God's mouth will not return empty but accomplishes its purpose. The irrepressible, effective word is the common motif against Paul's chains.

Low confidenceSo the word of the Lord grew mightily and prevailed; Isaiah's effectual word that accomplishes God's purpose underlies Luke's growth refrain. Faint, formulaic. Contested.
