'Means' in the Bible

When they had no means of repaying [the debts], he freely forgave them both. So which of them will love him more?”

For which one of you, when he wants to build a watchtower [for his guards], does not first sit down and calculate the cost, to see if he has enough to finish it?

And I tell you [learn from this], make friends for yourselves [for eternity] by means of the wealth of unrighteousness [that is, use material resources as a way to further the work of God], so that when it runs out, they will welcome you into the eternal dwellings.
