'Lack' in the Bible

And [when he] heard [this], Jesus said to him, "{You still lack one thing}: Sell all that you have, and distribute [the proceeds] to the poor--and you will have treasure in heaven--and come, follow me."

And he said to them, "When I sent you out without a money bag and a traveler's bag and sandals, you did not lack anything, [did you]?" And they said, "Nothing."
