Charles Ellicott Commentary Psalms 35:1

"Strive thou, O Jehovah, with them that strive with me: Fight thou against them that fight against me." — Psalms 35:1 (ASV)

Plead my cause. —Better, Strive, O Jehovah, with those who strive with me. The construction requires this, and the parallelism suggests recourse to arms rather than to the law.

Fight. —Literally, devour. (Compare to Numbers 24:8.

“He shall eat up the nations.” So a Latin author—
“Qua medius pugnæ vorat agmina vortex.”

SILIUS: Punic, 4:230.

Compare to Shakespeare—

“If the wars do not eat us up.”—Coriolanus, Acts 1, Scene 1)
