יהושע, פרק י״א, פסוק ח׳

After winning the battle with the help of God, the Israelites chased their fleeing enemies. They struck them a decisive blow, continuing the pursuit until no survivors remained.

The chase carried the Israelites to several distinct locations, including the great, heavily populated city of Tzidon. The specific designation of this city as large hints that there was another, smaller town that shared the exact same name [רד״ק].

The pursuers also reached another destination along the coast. The commentators agree unanimously that this site was a collection of salt pools. People would dig trenches and canals near the shore to gather seawater. As the intense heat of the sun burned and evaporated the trapped water, salt was left behind.
