'Panic' in the Bible

Then you will succeed, if you carefully obey the rules and regulations which the Lord ordered Moses to give to Israel. Be strong and brave! Don't be afraid and don't panic!

David said to his son Solomon: "Be strong and brave! Do it! Don't be afraid and don't panic! For the Lord God, my God, is with you. He will not leave you or abandon you before all the work for the service of the Lord's temple is finished.
