'Follow Me' in the Bible

After this Jesus left the place, and seeing a publican named Levi, sitting at the custom-house, he said to him, follow me.

Then he said to the whole company, if any one will be my follower, let him renounce himself, take up his cross daily, and follow me.

Then he said to another, follow me: but he replied, Lord, let me stay first, till I bury my father.

upon hearing that, Jesus said to him, one thing you have yet to do: sell all you have, and give it to the poor, and you shall have treasure in heaven: then come, and follow me.
