With this question, Yahweh emphasizes his authority to do as he pleases with Israel. Alternate translation: "I am allowed to act toward you, house of Israel, like the potter acts toward the clay." (See: [[rc://en/ta/man/jit/figs-rquestion]])
The word "house" is a metonym for the family that lives in the house. In this case it refers to the kingdom of Israel. See how you translated this in [Jeremiah 3:18](../03/18.md). Alternate translation: "Israel" or "kingdom of Israel" or "people of Israel" (See: [[rc://en/ta/man/jit/figs-metonymy]])
Yahweh speaks of himself by name to express the certainty of what he is declaring. See how you translated this in [Jeremiah 1:8](../01/08.md). Alternate translation: "this is what Yahweh has declared" or "this is what I, Yahweh, have declared" (See: [[rc://en/ta/man/jit/figs-123person]])
Yahweh compares his being able to remake Israel as he see fit to the way that the potter is able to remake a lump of clay as he sees fit. (See: [[rc://en/ta/man/jit/figs-simile]])
