Albert Barnes Commentary Psalms 35:26

"Let them be put to shame and confounded together that rejoice at my hurt: Let them be clothed with shame and dishonor that magnify themselves against me." — Psalms 35:26 (ASV)

Let them be ashamed ... - See the notes at (Psalms 35:4).

That magnify themselves against me - Who seek to exalt themselves over me; to make themselves great by humbling and destroying me. They hope to rise on my ruin.
