Zakharia 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.’

Zakharia 8:20-22

8:20 The Lord who rules over all says, ‘It will someday come to pass that people – residents of many cities – will come. 8:21 The inhabitants of one will go to another and say, “Let’s go up at once to ask the favor of the Lord, to seek the Lord who rules over all. Indeed, I’ll go with you.”’ 8:22 Many peoples and powerful nations will come to Jerusalem to seek the Lord who rules over all and to ask his favor.

[8:8]  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).
