Zechariah 8:8
8:8 And I will bring them to settle within Jerusalem. They will be my people, and I will be their God, 1 in truth and righteousness.’
1 sn The affirmation They will be my people, and I will be their God speaks of covenant renewal, a restoration of the unbroken fellowship the Lord desired to have with his people but which their disloyalty had shattered. In the eschaton God and Israel will be in covenant union once again (cf. Jer 31:33).
