דברי הימים ב, פרק כ״ו, פסוק ט״ו

King Uzziah’s reign marked an era of extraordinary military innovation and advanced strategic planning. By developing new weaponry, he transformed Jerusalem into a heavily fortified city, establishing a powerful reputation throughout the region. At the heart of this transformation were complex military inventions and war machines, born from deep study and sophisticated craftsmanship. The commentators agree that these devices were the result of intense planning and design.

[רש״י] compares this process to expert artistry, describing the tools as specialized siege engines crafted with great skill to batter walls. Building on this, [מלבי״ם] notes that Uzziah was highly skilled in mathematics and engineering. Through masterful design, he created machines capable of moving heavy loads and launching them easily over great distances, introducing new battle tactics that were previously unknown.

These advanced weapons were positioned strategically across the city defenses. They were mounted on watchtowers and set upon high, tower-like structures built into the corners of the walls [מצודת ציון]. From these elevated points, the machines were designed to shoot or hurl massive arrows and heavy stones with tremendous force at the enemy [מצודת ציון].

Because of these groundbreaking developments, the king's fame spread far beyond his borders. He achieved wondrous feats, using his inventions to build his strength and protect his people [מצודת דוד]. Although he governed a relatively small nation, he methodically advanced his military and fortified his cities step by step, ultimately rising as a leader with a formidable and deterring military presence [ביאור שטיינזלץ].
