'Merrily' in the Bible

David and all Israel celebrated [joyfully] before God with all their might, with songs, lyres, harps, tambourines, cymbals, and trumpets.

Then said Zeresh his wife and all his friends unto him, Let a gallows be made of fifty cubits high, and to morrow speak thou unto the king that Mordecai may be hanged thereon: then go thou in merrily with the king unto the banquet. And the thing pleased Haman; and he caused the gallows to be made.

And I will say to my soul, “Soul, you have many good things stored up, [enough] for many years; rest and relax, eat, drink and be merry (celebrate continually).”’
