Isaiah 54:1-2

Amplified Bible

54 “Shout for joy, O barren one, she who has not given birth;
Break forth into joyful shouting and rejoice, she who has not gone into labor [with child]!
For the [spiritual] sons of the desolate one will be more numerous
Than the sons of the married woman,” says the Lord.^(A)
2 
“Enlarge the site of your tent [to make room for more children];
Stretch out the curtains of your dwellings, do not spare them;
Lengthen your tent ropes
And make your pegs (stakes) firm [in the ground].
