Isaiah 54:12

10 Though the mountains may be removed and the hills may be shaken, My loving devotion will not depart from you, and My covenant of peace will not be broken,” says the LORD, who has compassion on you.

11 “O afflicted city, lashed by storms, without solace, surely I will set your stones in antimony and lay your foundations with sapphires.

I will make your pinnacles of rubies, your gates of sparkling jewels, and all your walls of precious stones.

13 Then all your sons will be taught by the LORD, and great will be their prosperity.

14 In righteousness you will be established, far from oppression, for you will have no fear. Terror will be far removed, for it will not come near you.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
