You need not take up arms, yet perhaps you may have to do so; you need not cross the seas, yet it may be that you will pay your debt, even when the wind threatens to blow a gale. Do you wish to return the benefit? Then receive it graciously; you have then returned the favour⁠—not, indeed, so that you can think yourself to have repaid it, but so that you can owe it with a quieter conscience.
