The journey back from exile included more than just the Israelites; it involved specific groups of servants whose lives were deeply intertwined with the nation. These temple workers and the descendants of Solomon's servants were actually of Canaanite origin. Over the course of hundreds of years, they lived alongside the Israelites, building a long history of shared existence [ביאור שטיינזלץ].
Although one group carried the title of Solomon's servants, they were not the original workers who served the ancient king. Rather, they were the distant grandchildren and later generations who simply kept the historical name alive [רש״י]. Together, the combined count of the men returning from these specific historical groups reached three hundred and ninety-two.
