First of all, the knowledge is the instruction that the priests had to give about the law and God’s great deeds. But it is also about knowing-in-love. If you really like someone, you want to get to know him or her better. This also applies to the relationship with God: Bible study is extremely important, especially within the relationship of love with the Lord God. Knowledge is: a sure knowledge and a firm trust, this combination. Here also applies: if knowledge is lacking, love for and loyalty to God also disappear. And then people start living liberally. As a result, they perish. The downfall begins where the spiritual leaders start neglecting biblical teaching!
6 My people are destroyed for lack of knowledge; because you have rejected knowledge, I reject you from being a priest to me. And since you have forgotten the law of your God, I also will forget your children.
