God charges that all categories of sinners are adulterers! He uses the normal word for adultery. He then provides insight into one way the spirit of harlotry entered into Israelite culture: "They do not consider in their hearts"! Is this not also true today? Despite all the evidence of how destructive sexual sins are, people will not change! Within marriage and society at large, we see syphilis, gonorrhea, herpes, chlamydia, AIDS, broken homes, rebellious children, and children being raised by single parents. How many children are not even sure who their parents are? These sins are tearing the nation apart!
The Hebrew word underlying the word "king" in Hosea 7:3 is sometimes used to indicate leaders in business, education, and government, not just the head of the government. God is pointing an accusing finger at those whose own evil ends are to profit from this cesspool of faithlessness—to make money and gain power. This list can include doctors, lawyers, hospitals, pharmaceutical houses, pornographers, booksellers, moviemakers, etc.
