Psalms 104:12

By them shall the fowls of the heaven have their habitation - Among them the fowls of the air dwell. That is, among the trees which spring up by the fountains and water-courses. The whole picture is full of animation and beauty.

Which sing among the branches - Margin, as in Hebrew, “give a voice.” Their voice is heard - their sweet music - in the foliage of the trees which grow on the margin of the streams and by the fountains. There is scarcely to be found a more beautiful poetic image than this.
