'Follow Me' in the Bible

After these things he went out, and saw a tax collector named Levi sitting at the tax office, and said to him, "Follow me."

He said to all, "If anyone desires to come after me, let him deny himself, take up his cross daily, and follow me.

He said to another, "Follow me." But he said, "Lord, allow me first to go and bury my father."

When Jesus heard it, he said to him, "You still lack one thing. Sell all that you have, and distribute it to the poor. You will have treasure in heaven. Come, follow me."
