"My people are destroyed for lack of knowledge, because you have rejected knowledge, I also will reject you from being priest for Me. Because you have forgotten the law Your God, I will also forget your children."
This Scripture has often been taught to the members that we are destroyed due to lack of knowledge.The passage means due to Israel's religious leaders that caused the people's downfall. The priest failed to teach God's law to the people in other words, God's Word.(Mal 2:7). In the Old Testament, the prophets was commonly called a Messenger of the Lord. This is the only time that the priest are called the Messengers of the Lord.
Yes,if the people aren't taught the Word of God correctly by the priestly line, then God will deal with His priest. As a result, the priests would be the special object of God's judment. He would terminate the priestly line.
