Zechariah 1:12

The angel of the Lord then asked, “Lord who rules over all, ¹  how long before you have compassion on Jerusalem ²  and the other cities of Judah which you have been so angry with for these seventy years?” ³ 

Then the angel of the LORD said, "LORD Almighty, how long will you withhold mercy from Jerusalem and from the towns of Judah, which you have been angry with these seventy years?"

Then the angel of the LORD said, "O LORD of hosts, how long will You have no compassion for Jerusalem and the cities of Judah, with which You have been indignant these seventy years?"

Upon hearing this, the angel of the LORD prayed this prayer: "O LORD Almighty, for seventy years now you have been angry with Jerusalem and the towns of Judah. How long will it be until you again show mercy to them?"

The Angel of GOD reported back, "O GOD-of-the-Angel-Armies, how long are you going to stay angry with Jerusalem and the cities of Judah? When are you going to let up? Isn't seventy years long enough?"

Then the angel of the Lord, answering, said, O Lord of armies, how long will it be before you have mercy on Jerusalem and on the towns of Judah against which your wrath has been burning for seventy years?

Then the angel of the LORD said, "O LORD of hosts, how long will you withhold mercy from Jerusalem and the cities of Judah, with which you have been angry these seventy years?"

Then the Angel of the LORD answered and said, "O LORD of hosts, how long will You not have mercy on Jerusalem and on the cities of Judah, against which You were angry these seventy years?"

The angel of the Lord then asked, “Lord who rules over all, ¹  how long before you have compassion on Jerusalem ²  and the other cities of Judah which you have been so angry with for these seventy years?” ³ 

¹ sn Note that here the angel of the Lord is clearly distinct from the Lord who rules over all himself.

³ sn The seventy years refers to the predicted period of Babylonian exile, a period with flexible beginning and ending points depending on the particular circumstances in view (cf. Jer 25:1; 28:1; 29:10; Dan 9:2). Here the end of the seventy years appears to be marked by the completion of the temple in 516 b.c., exactly seventy years after its destruction in 586.
