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 Mon peuple est détruit, parce qu'il lui manque la connaissance. Puisque tu as rejeté la connaissance, Je te rejetterai, et tu seras dépouillé de mon sacerdoce; Puisque tu as oublié la loi de ton Dieu, J'oublierai aussi tes enfants.
