Why withdrawest thou thy hand, even thy right hand? Why dost thou keep back the right hand of thy power, hiding it in thy besom? Why not show forth thy power, and consume them, as it were, in a moment?
(See the next clause.) Pluck it out of thy bosom; rather, out with it frown thy bosom, and consume them. The psalmist sees no reason why the Babylonians should not be consumed, and Israel delivered, at once.
He has an insufficient sense of the greatness of Israel's sin.
