sn These covenant promises are being reiterated here because they are about to be fulfilled. They are addressed to the nation, not individuals, as the plural suffixes show. Yahweh was their God already, because they had been praying to him and he is acting on their behalf. When they enter into covenant with God at Sinai, then he will be the God of Israel in a new way (19:4–6; cf. Gen 17:7–8; 28:20–22; Lev 26:11–12; Jer 24:7; Ezek 11:17–20).
