'Follow Me' in the Bible

And after these things he went forth, and saw a publican, named Levi, sitting at the receipt of custom, and said to him, Follow me.

And he said to all, if any man be willing to come after me, let him deny himself, and take up his cross daily and follow me.

And he said to another, Follow me.

Sell all that thou hast, and distribute to the poor, and thou shalt have treasure in heaven; and come, follow me.
