'Begun' in the Bible

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.

O Lord Jehovah, thou hast begun to show thy servant thy greatness, and thy strong hand: for what god is there in heaven or in earth, that can do according to thy works, and according to thy mighty acts?
