Charles Spurgeon Commentary Nahum 3:4-5

"because of the multitude of the whoredoms of the well-favored harlot, the mistress of witchcrafts, that selleth nations through her whoredoms, and families through her witchcrafts. Behold, I am against thee, saith Jehovah of hosts, and I will uncover thy skirts upon thy face; and I will show the nations thy nakedness, and the kingdoms thy shame." — Nahum 3:4-5 (ASV)

Because of the multitude of the whoredoms of the well-favored harlot, the mistress of witchcrafts, that sells nations through her whoredoms, and families through her witchcrafts. Behold, I am against you, says the LORD of hosts;

These people had been steeped in sin of the worst kind; they had led other nations into it; and had practiced the witchcrafts which God abhors. Therefore again Jehovah says, I am against you.

When God is in arms against a triumphant nation, he soon makes an end of it.
