Zakharia 13:9

13:9 Then I will bring the remaining third into the fire;

I will refine them like silver is refined

and will test them like gold is tested.

They will call on my name and I will answer;

I will say, ‘These are my people,’

and they will say, ‘The Lord is my God.’” ¹ 

¹ sn The expression I will say ‘It is my people,’ and they will say ‘the Lord is my God’ is reminiscent of the restoration of Israel predicted by Hosea, who said that those who had been rejected as God’s people would be reclaimed and once more become his sons and daughters (Hos 2:23).
