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 Israelite people group" (See: [[rc://en/ta/man/jit/figs-metonymy]])
These phrases are both ways the people of Israel are saying Ezekiel's warnings will not happen in their lifetime but will happen far in the future. (See: [[rc://en/ta/man/jit/figs-parallelism]])
