'Follow Me' in the Bible

And after these things he went out and saw a publican by the name of Levi, sitting at the custom house, and said to him, Follow me.

And he said to all, If any one wishes to come after me, let him deny himself, and take up his cross, and follow me.

And he said to another, Follow me. And he said, Lord, permit me first to go and bury my father.

And Jesus hearing it, said to him, One thing you yet want; sell all that you have, and distribute to the poor, and you shall have a treasure in heaven, and come, follow me.
