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](../03/17.md). AT: "Israel" or "the kingdom of Israel" or "the people of Israel" (See: [[rc://en/ta/man/translate/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](../01/07.md). AT: "this is what Yahweh has declared" or "this is what I, Yahweh, have declared" (See: [[rc://en/ta/man/translate/figs-123person]])
# I will place my law within them and will write it on their heart
These two phrases have similar meanings and emphasize that Yahweh's law will become a part of them, rather than merely written on stone. Here "heart" represents "emotions" or "mind." AT: "My law will be part of their thoughts and emotions" (See: [[rc://en/ta/man/translate/figs-parallelism]] and [[rc://en/ta/man/translate/figs-metonymy]])
This phrase refers to every person, from the least important to the most important. AT: "every single one of them" (See: [[rc://en/ta/man/translate/figs-merism]])
