Holy king, justice, and remembered mediators

The king between the cherubim is holy, and his strength loves judgment

The LORD reigneth; let the people tremble: he sitteth between the cherubims; let the earth be moved. The LORD is great in Zion; and he is high above all the people. Let them praise thy great and terrible name; for it is holy. The king's strength also loveth judgment; thou dost establish equity, thou executest judgment and righteousness in Jacob.

Cherubim place the reign at the ark's throne imagery. Trembling and a moved earth match holiness, not entertainment. Equity and righteousness in Jacob keep kingship tied to justice inside Israel. Holy is not a mood. It is the name that requires fair dealing.

Moses, Aaron, and Samuel are remembered as answered mediators, forgiven and still corrected

Exalt ye the LORD our God, and worship at his footstool; for he is holy. Moses and Aaron among his priests, and Samuel among them that call upon his name; they called upon the LORD, and he answered them. He spake unto them in the cloudy pillar: they kept his testimonies, and the ordinance that he gave them.

Thou answeredst them, O LORD our God: thou wast a God that forgavest them, though thou tookest vengeance of their inventions. Exalt the LORD our God, and worship at his holy hill; for the LORD our God is holy. The three names model intercession that is heard. Forgiveness and vengeance on inventions stand together. Holiness does not transfer unchecked authority to later religious leaders, and it does not make Israel's mediators mascots for a different people's power.
