New Defender's Study Bible Notes
9:2 six men. These men were evidently angels appearing in the form of men.
9:3 gone up. In vision, Ezekiel here sees the presence of God beginning to depart from Israel, first of all leaving His place between the golden cherubim over the ark in the temple, to go to the threshold of the house. Next He would leave the threshold, then the temple and the city (Ezekiel 10:18; 11:23).
9:6 the mark. The “mark upon the foreheads” (Ezekiel 9:4) is evidently similar to the future angelic seal which will be placed on “the servants of our God in their foreheads” (Revelation 7:3) during the coming period of great tribulation. These faithful Jews were to be supernaturally protected from slaughter in God’s terrible judgment on Israel’s apostasy.
9:6 begin at my sanctuary. A comprehensive principle of divine judgment is that “unto whomsoever much is given, of him shall be much required” (Luke 12:48). “Judgment must begin at the house of God” (I Peter 4:17). “Be not many masters, knowing that we shall receive the greater condemnation” (James 3:1). The people of Israel and Judah had been led into apostasy by their leaders, including especially false prophets and worldly priests.
