Khema: Safety
Khema is ground where nothing can reach you. Rest from all your enemies comes to David as a gift handed over, not a prize won at the end of one more campaign, and it arrives while he is still a soldier with a standing army. A bolted door makes a house safe for the night; this other safety belongs to whoever no longer needs the bolt.
Averā: Freedom from enmity
Averā is the condition in which no one stands as your opponent. Enemies fall silent one by one as the hostility that made them enemies dies down, and David's roll of Philistines and Ammonites can shorten from his side as much as from theirs. Hatred put down by hatred only changes hands, the way a debt passes from one heir to the next.
Gahakāraka: The house builder
Gahakāraka is the craving that raises one dwelling after another. David has cedar, masons, and a temple drawn up in his head, and the word Nathan brings back takes the trowel out of his hand: you will not build, you will be built. Spotting the builder is what stops the building, and the house standing afterward is one nobody had to lift a stone for.
Saṅkhāra: Things put together
Saṅkhāra covers whatever is assembled out of parts. A house of cedar is beams, pegs, and hired labor; a house of descendants is marriages, births, and survival, and each holds only as long as its pieces do. Solomon's temple burned and the throne emptied on the ordinary schedule of assembled things, which pushes the promised house toward something no one put together.
Anattā: Not-self
Anattā is the absence of an owner inside anything. The house being made here is a line of sons who each arrive through conditions no father arranges, so the name David rests on it the way a family name rests on a shop that has changed hands for generations. Gripping a dynasty as mine is the same grip he would have taken on a temple built with his own money, and the grip is exactly what is being lifted.
