'Begin' in the Bible

Rise ye up, take your journey, and pass over the valley of the Arnon: behold, I have given into thy hand Sihon the Amorite, king of Heshbon, and his land; begin to possess it, and contend with him in battle.

This day will I begin to put the dread of thee and the fear of thee upon the peoples that are under the whole heaven, who shall hear the report of thee, and shall tremble, and be in anguish because of thee.

And Jehovah said unto me, Behold, I have begun to deliver up Sihon and his land before thee: begin to possess, that thou mayest inherit his land.

Seven weeks shalt thou number unto thee: from the time thou beginnest to put the sickle to the standing grain shalt thou begin to number seven weeks.
