'Follow Me' in the Bible

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

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

And he said to another, Follow me. And he said, Lord, permit me having gone, first to inter my father.

And Jesus having heard these, said to him, Yet one thing fails thee: all whatever thou hast, sell and distribute to the poor, and thou shalt have treasure in heaven: and come, follow me.
