Yahweh being good and faithful to a person is spoken of as if goodness and covenant faithfulness are things that pursue after a person. The abstract nouns "goodness" and "faithfulness" can be translated as adjectives. Alternate translation: "Surely you will be good and faithful to me" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-abstractnouns]])
Possible meanings are that 1) this refers to Yahweh's eternal home, or 2) this refers to Yahweh's temple in Jerusalem. If possible, translate it so that both meanings could be understood.
