John Gill Commentary Psalms 41:7

"All that hate me whisper together against me; Against me do they devise my hurt." — Psalms 41:7 (ASV)

All that hate me whisper together against me
That is, they privately conspired against him; see (Matthew 22:15) (John 11:53) (Matthew 26:3Matthew 26:4) ;

against me do they devise my hurt ;
not only to take away his name and credit, but his life.
