But thou hast cast off, and put us to shame; and goest not forth with our armies.
But - literally, 'Also' х 'ap (H637)]: there is some such ellipsis as this-We are "all the day long" (Psalms 44:8) expecting deliverance; but not only hast thou not delivered us, but 'ALSO thou hast cast us off.'
And goest not forth with our armies. Contrast 2 Samuel 5:24, where the Lord gives a response to David on the latter consulting the divine oracle, "The Lord shall go out before thee, to smite the host of the Philistines."
