'Finish' in the Bible

"Go," He replied, "and take this message to that fox: "'See, to-day and to-morrow I am driving out demons and effecting cures, and on the third day I finish my course.'

"Which of you, desiring to build a tower, does not sit down first and calculate the cost, asking if he has the means to finish it? --

lest perhaps, when he has laid the foundation and is unable to finish, all who see it shall begin to jeer at him,

saying, 'This man began to build, but could not finish.'
