By them shall the fowls of the heaven have their habitation,.... Another use of the springs, fountains, and rivers of water; by the sides and on the shores of these, some birds delight to be, and on trees that grow here do they build their nests; and here, having wetted their throats, they sit, and chirp, and sing: to doves, by rivers of water, is the allusion in Sol 5:12. Which sing among the branches; of trees that grow by the sides of fountains and rivers; see Eze 17:23. To such birds may saints be compared; being, like them, weak, defenceless, and timorous; liable to be taken in snares, and sometimes wonderfully delivered; as well as given to wanderings and strayings: and to fowls of the heaven, being heaven born souls, and partakers of the heavenly calling. These have their habitation by the fountain of Jacob, by the river of divine love, beside the still waters of the sanctuary; where they sing the songs of Zion, the songs of electing, redeeming, and calling grace.
