Hosea 4:6 says God's people are destroyed for lack of what?

Answer: Knowledge

"My people are destroyed for lack of knowledge," because they had rejected knowledge and forgotten the law of their God.

“My people are destroyed for lack of knowledge. Because you have rejected knowledge, I will also reject you as My priests. Since you have forgotten the law of your God, I will also forget your children.”— Hosea 4:6 (BSB)
