'Follow Me' in the Bible

After this He went out and noticed a tax-gatherer, Levi by name, sitting at the Toll office; and He said to him, "Follow me."

"Follow me," He said to another. "Master," the man replied, "allow me first to go and bury my father."

On receiving this answer Jesus said to him, "There is still one thing wanting in you. Sell everything you possess and give the money to the poor, and you shall have wealth in Heaven; and then come, follow me."
