Matthew Poole and continuators on Psalms 102:7

7 I watch, and am as a sparrow alone upon the house-top.

Which hath lost its Mate, and then is very sad and solitary, as some report; although that be uncertain and improbable. But this Hebrew word doth not onely signifie a Sparrow, but in general any Bird, as Levit▪ 14. 4. Deut. 14. 11. Dan. 4. 9, 11, 30. And so it may here design any one or more sort of Birds, which used to sit alone watching and mourning upon house-tops.
