John Gill Commentary Psalms 80:6

"Thou makest us a strife unto our neighbors; And our enemies laugh among themselves." — Psalms 80:6 (ASV)

You make us a strife to our neighbours
Either obliges us to contend with them for our defence and safety; or having given us into their hands, they strive and contend one with another about dividing the spoil:

and our enemies laugh among themselves ;
at us, and because there is no help for us in God, as they imagine; or at God himself, as Kimchi, saying he cannot save as.
