And there he maketh the hungry to dwell, that they may prepare a city for habitation;

Wesley's Notes

107:36 Hungry - Poor people who could not provide for themselves.

Matthew Henry's Concise Commentary

107:33-43 What surprising changes are often made in the affairs of men! Let the present desolate state of Judea, and of other countries, explain this. If we look abroad in the world, we see many greatly increase, whose beginning was small. We see many who have thus suddenly risen, as suddenly brought to nothing. Worldly wealth is uncertain; often those who are filled with it, ere they are aware, lose it again. God has many ways of making men poor. The righteous shall rejoice. It shall fully convince all those who deny the Divine Providence. When sinners see how justly God takes away the gifts they have abused, they will not have a word to say. It is of great use to us to be fully assured of God's goodness, and duly affected with it. It is our wisdom to mind our duty, and to refer our comfort to him. A truly wise person will treasure in his heart this delightful psalm. From it, he will fully understand the weakness and wretchedness of man, and the power and loving-kindness of God, not for our merit, but for his mercy's sake.
