"But the general slaughter of all those who do not thus see the wide contrast between sin and righteousness, and do not feel as those do who stand in the counsel of God and receive the mark, is described in the order to the five men with slaughter weapons: “Go ye after him through the city, and smite: let not your eye spare, neither have ye pity: slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at My sanctuary.” 3T 267.2"
"And to the others he said in mine hearing, Go ye after him through the city, and smite: let not your eye spare, neither have ye pity: Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at my sanctuary. Then they began at the ancient men which were before the house."
EGW directly quotes Ezekiel 9:5-6 and uses it as a basis for her commentary on the separation of the righteous and the wicked.
"raise their voice against sin and wrong, but whose sympathies are ever found with those who trouble the camp of Israel with their sins? Said God to Joshua: “Thou canst not stand before thine enemies, until ye take away the accursed thing from among you.” He pronounced the punishment which would follow the transgression of His covenant. 3T 267.3"
"Up, sanctify the people, and say, Sanctify yourselves against to morrow: for thus saith the Lord God of Israel, There is an accursed thing in the midst of thee, O Israel: thou canst not stand before thine enemies, until ye take away the accursed thing from among you."
EGW directly quotes Joshua 7:13 and uses it to illustrate the need to remove sin from the camp of Israel.
