Yesaya 29:2

29:2 I will threaten Ariel,

and she will mourn intensely

and become like an altar hearth ¹  before me.

Yesaya 44:17

44:17 With the rest of it he makes a god, his idol;

he bows down to it and worships it.

He prays to it, saying,

‘Rescue me, for you are my god!’

[29:2]  ¹ tn The term אֲרִיאֵל (’ari’el, “Ariel”) is the word translated “altar hearth” here. The point of the simile is not entirely clear. Perhaps the image likens Jerusalem’s coming crisis to a sacrificial fire.
