Following the completion of his massive building projects, Solomon embarks on another major enterprise that highlights the vast reach and power of his kingdom [מצודת דוד]. The primary approach among commentators is that his journey into these new areas was a military campaign aimed at conquering the cities [מצודת דוד, רד״ק, מלבי״ם].
Once he successfully took control of these territories, Solomon established a naval fleet. This historical detail is further explained and completed by the parallel account found in the Book of Kings [רד״ק, מלבי״ם, חומת אנך]. The specific coastal region where he built and stationed this fleet was along the shores of the Red Sea [ביאור שטיינזלץ].
