Jeremiah 29:12

and if they return to You with all their heart and with all their soul in the land of their captivity, where they have been taken captive, and pray toward their land which You have given to their fathers and the city which You have chosen, and toward the house which I have built for Your name,

‘Call to Me and I will answer you, and I will tell you great and mighty things, which you do not know.’

“And I will bring the third part through the fire And refine them as silver is refined And test them as gold is tested. They will call on My name, And I will answer them; I will say, ‘They are My people,’ And they will say, ‘Yahweh is my God.’”
