Charles Ellicott Commentary Psalms 60:1

"O God thou hast cast us off, thou hast broken us down; Thou hast been angry; oh restore us again." — Psalms 60:1 (ASV)

Have scattered us. —Literally, have broken us. A word applied to a wall or fence, Psalms 80:12, but in 2 Samuel 5:20 applied to the rout of an army, an event which gave its name to the locality, “plain of breaches.” So in English:

“And seeing me, with a great voice he cried,
They are broken, they are broken.”—

TENNYSON: Elaine.

On the other hand, the two succeeding verses seem to refer to a political convulsion rather than a military defeat, and it has been conjectured that the breach between the two kingdoms is here indicated. (See the use of perez=breach, in Judges 21:15.)
