David solicits God to the speedy destruction of the wicked and the preservation of the godly, 1-5.
1 [To the Chief Musician. A Psalm of David: to bring to remembrance.] Make haste, O God, to deliver me. Make haste to help me, O LORD.
2 Let them be ashamed and confounded who seek after my soul. Let them be turned backward and put to shame who desire my hurt.
3 Let them be turned back for a reward of their shame who say, "Aha, aha."
4 Let all those who seek you rejoice and be glad in you. And let those who love your salvation say continually, "Let God be magnified."
5 But I am poor and needy. Make haste to me, O God. You are my help and my deliverer. O LORD, make no delay.
Matthew Henry Commentary - Psalms, Chapter 70[➚]
John Calvin's Chapter Summary:
This psalm is merely a part of the fortieth, and the inscription, To call to remembrance, is perhaps designed to indicate this; David having taken these five verses out of that other psalm, and accommodated them for being used on some particular occasion. I shall only here repeat the words of the text; and would refer the reader for the interpretation to the proper place.
