The word "house" is a metonym for the family that lives in the house, in this case the Israelites, the descendants of Jacob over many years. See how you translated this in [Ezekiel 3:1](../03/01.md). Alternate translation: "the Israelites" or "the Israelite people group" (See: [[rc://en/ta/man/translate/figs-metonymy]])
In Jewish law, a dead body defiled anything it touched and made it "unclean." Burying these bodies is spoken of as cleansing or purifying the land. (See: [[rc://en/ta/man/translate/figs-explicit]])
