78Cause the proud people who falsely accuse me to be ashamed, but as for me, I will continue ◄meditating on/thinking about► ◄your principles of behavior/what you have declared that we should do►.
79Cause those who revere you to come back to me in order that they may (OR, specifically, those who) know ◄your requirements/what you have instructed us to do►.
80Enable me to perfectly obey ◄your statutes/what you have decreed that we should do► in order that I may not be ashamed because of not doing that.
81I am very tired/exhausted while I wait for you to save me from my enemies; but I confidently expect that you will tell me what you will do.
