Charles Spurgeon Commentary 2 Chronicles 12:3-4

"with twelve hundred chariots, and threescore thousand horsemen. And the people were without number that came with him out of Egypt: the Lubim, the Sukkiim, and the Ethiopians. And he took the fortified cities which pertained to Judah, and came unto Jerusalem." — 2 Chronicles 12:3-4 (ASV)

With twelve hundred chariots, and threescore thousand horsemen: and the people were without number that came with him out of Egypt; the Lubims, the Sukkiims, and the Ethiopians. And he took the fenced cities which pertained to Judah, and came to Jerusalem.

How vain is man when he boasts in the strength of his fortifications! These fenced cities fell at once, like houses built of cards, before the power of the mighty king of Egypt, and the vast hordes that accompanied him. Rehoboam had spent his strength in making these defenses, but how soon they were proved to be worthless.

Blessed is the man that trusteth in the Lord, and whose hope the Lord is; but cursed is the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the Lord.
