«وَتَخْشَى النَّاسَ وَاللَّهُ أَحَقُّ أَنْ تَخْشَاهُ»
You fear people, while God is more deserving that you fear Him.
Takhshā appears earlier and takhshāhu closes the expression. The verbs share a root and a strongly linked meaning. The verbal return reinforces the redirection of fear to God.
The example shows that the verbal figure can serve the thought rather than merely repeating a sound.
