Their land also is full of silver and gold, neither is there any end of their treasures; their land is also full of horses, neither is there any end of their chariots:
Their land also is full of silver and gold - forbidden to be heaped together, Deuteronomy 17:17. Solomon disobeyed (1 Kings 10:21; 1 Kings 10:27).
Horses ... chariots - forbidden, Deuteronomy 17:16. Solomon disobeyed (1 Kings 10:26). Horses could be used effectively for war in the plains of Egypt; not so in the hilly Judea. God designed there should be as wide as possible a distinction between Israel and the Egyptians. He would have his people wholly dependent on Him, rather than on the ordinary means of warfare (Psalms 20:7). Also, horses were connected with idolatry (2 Kings 23:11): so the transition to "idols" (Isaiah 2:8) is natural.
