Albert Barnes Commentary Psalms 83:1

"O God, keep not thou silence: Hold not thy peace, and be not still, O God." — Psalms 83:1 (ASV)

Keep not thou silence, O God - See the notes at (Psalms 28:1). The prayer here is that in the existing emergency God would not seem to be indifferent to the needs and dangers of His people, and to the purposes of their enemies, but that He would speak with a voice of command, and break up their designs.

Hold not thy peace - That is, Speak. Give command. Disperse them by Your own authority.

And be not still, O God - Awake; arouse; do not be indifferent to the needs and dangers of Your people. All this is the language of petition, not of command. Its rapidity, its repetition, its tone, all denote that the danger was imminent, and that the necessity for divine interposition was urgent.
