7 Let them disappear like water that flows away. Let them wither like grass.
Darby
7 Let them melt away as waters that flow off; when he aimeth his arrows, let them be as blunted:
KJV
7 Let them melt away as waters [which] run continually: [when] he bendeth [his bow to shoot] his arrows, let them be as cut in pieces.
