Joel does not mention what he longs for. On the one hand it speaks for itself what he yearns for (look at the disastrous state of the land, the complaint of even the animals). On the other hand he reverently leaves it to God. He does offer some proposals: a gathering of mourning, repentance, and invocation of the Lord, but he does not want to get in the way of God. No one knows better than God himself what is needed for new joy. May God give what is needed. Humbly Joel limits himself to an upward cry.
19 C'est vers toi que je crie, ô Eternel! Car le feu a dévoré les plaines du désert, Et la flamme a brûlé tous les arbres des champs.
