John Gill Commentary Psalms 34:14

"Depart from evil, and do good; Seek peace, and pursue it." — Psalms 34:14 (ASV)

Depart from evil
This denotes that evil is near to men; it keeps close to them, and should be declined and shunned: and it regards all sorts of evil; evil men, and their evil company; evil things, evil words and works, and all appearance of evil; and the fear of the Lord shows itself in an hatred of it, and a departure from it, (Proverbs 8:13) (16:6) ;

and do good ;
not only acts of beneficence to all in necessitous circumstances, but every good work; whatever the word of God directs, or suggests should be done; and which should be done from right principles of faith and love, and to right ends, the glory of God, and the good of his interest; and Christ should be looked and applied unto for grace and strength to perform; all which are evidences of the true fear of God;

seek peace, and pursue it ;
in the world, and with all men, as much as possibly can be; in neighbourhoods, cities, and states, and in the churches of Christ, and with the saints, as well as with God through Christ; and which in every sense is to be pursued after with eagerness, and to be endeavoured for with diligence; see (Romans 12:18) (14:19) (Hebrews 12:14) .
