Hosea 4:6-7

My people are destroyed for lack of knowledge [of My law, where I reveal My will]. Because you [the priestly nation] have rejected knowledge, I will also reject you from being My priest. Since you have forgotten the law of your God, I will also forget your children. ¶The more they multiplied [in numbers and increased in power], the more they sinned against Me; I will change their glory into shame.
