Jeremiah 31:39

“Thus says Yahweh, ‘Behold, I will return the fortunes of the tents of Jacob And have compassion on his dwelling places; And the city will be rebuilt on its ruin, And the palace will sit on its just place.

‘Therefore thus says Yahweh, “I will return to Jerusalem with compassion; My house will be built in it,” declares Yahweh of hosts, “and a measuring line will be stretched over Jerusalem.”’

Then I lifted up my eyes and saw, and behold, there was a man with a measuring cord in his hand.

So I said, “Where are you going?” And he said to me, “To measure Jerusalem, to see how wide it is and how long it is.”
