Deuteronomy 28:32

Thy sons and thy daughters [shall be] given unto another people, and thine eyes shall look, and fail [with longing] for them all the day long: and [there shall be] no might in thine hand.

Ver. 32. And thine eyes shall look.] A sad sight to see our children butchered before our eyes, as Mauricius the Emperor did; or otherwise misused by a merciless enemy. Doves sometimes sit in their dove-cotes and see their nests destroyed, their young ones taken away and killed before their eyes, neither do they ever offer to rescue or revenge, as all other creatures either do or desire to do.

And fail with looking.] As Sisera's mother's did. Jdg 5:28
