After seventy years God was faithful to deliver Judah as promised.

Zechariah 1:12-17
New Living Translation (NLT)

12 Upon hearing this, the angel of the Lord prayed this prayer: “O Lord of Heaven’s Armies, for seventy years now you have been angry with Jerusalem and the towns of Judah. How long until you again show mercy to them?” 13 And the Lord spoke kind and comforting words to the angel who talked with me.

14 Then the angel said to me, “Shout this message for all to hear: ‘This is what the Lord of Heaven’s Armies says: My love for Jerusalem and Mount Zion is passionate and strong. 15 But I am very angry with the other nations that are now enjoying peace and security. I was only a little angry with my people, but the nations inflicted harm on them far beyond my intentions.

16 “‘Therefore, this is what the Lord says: I have returned to show mercy to Jerusalem. My Temple will be rebuilt, says the Lord of Heaven’s Armies, and measurements will be taken for the reconstruction of Jerusalem.[a]’

17 “Say this also: ‘This is what the Lord of Heaven’s Armies says: The towns of Israel will again overflow with prosperity, and the Lord will again comfort Zion and choose Jerusalem as his own.’”
