“Some wandered in the desert wastes.
They found no way to an inhabited town.
They were hungry and thirsty.
Their soul fainted within them.
Then they cried to Yahweh in their trouble.
He delivered them from their distress.
He led them by a straight way.
They finally reached an inhabited town.
Let them thank Yahweh
For his steadfast love!
Let them thank Yahweh
For his wonderful works to humankind!
He satisfies the thirsty.
He fills the hungry with good things.”
This section points out how Yahweh has helped those wandering Israelites in the desert. I am not sure what particular event this refers to since these wanderers seem to be looking for inhabited towns. This does not seem to be a reference to the 40 years of wandering in the desert, but a smaller group of lost Israelites who were hungry and thirsty. Their souls were fainting. In their distress they called out to Yahweh. Yahweh heard them. He led them in a straight path to an inhabited town. Thus they have to give thanks again to Yahweh for his steadfast love and the all the works that he has done for all humans. He has satisfied the thirsty. He has filled the hungry with good food.
