These 2 chapters are about the hardness of heart that is idolatrous and brings severe judgment. First God reveals his truth so that they have no excuse and when they harden their hearts it results in judgments. Israel came out of Egypt accompanied with great judgments upon the Egyptians with very supernatural signs and wonders. The Lord’s glory leaves the house of Israel because it has become corrupt and idolatrous like the Egyptians with the result of great judgments and the captivity of the nation in order to purify them and bring forth the remnant. 2nd John 1 reveals the importance of walking in the truth and not sparing those that deny that Jesus Christ is come in the flesh and therefore deny the truth. This is 1 of the main keys to overcoming corruption. The other is in the 4 faces of the cherubim.
