Therefore thou shalt have none that shall cast a cord by lot in the congregation of the LORD.
Therefore - resumed from Micah 2:3. On account of your crimes, described in Micah 2:1-2.
Thou - the ideal individual ("me," Micah 2:4), representing the guilty people in whose name he spoke.
Thou shalt have none that shall cast a cord by lot - none who shall have any possession measured out. God had originally divided to Israel the land by lot, using a line or cord for measurement (Joshua 13:6, the Lord said to Joshua, "Divide thou it by lot unto the Israelites for an inheritance"). Such a distribution or division of Israel's inheritance was now about to be made by Israel's enemy, not by Israel herself.
In the congregation of the Lord - among the people consecrated to Yahweh. By covetousness and violence (Micah 2:2) they had forfeited "the portion of Yahweh's people" (Micah 2:4). This is God's implied answer to their complaint of injustice, "He hath changed the portion of my people." God replies, they shall no longer be reckoned "in the congregation of the Lord" (Ezekiel 13:9, "They shall not be in the assembly of my people"): nor as such divide inheritances by lot. The congregation of the Lord х qaahaal (H6951) Yahweh (H3068)] was the court before which the assignment or inheritances was decided.
