Genesis 43:11

If it must be so now, take your brother — If no corn can be had but upon those terms, as good expose him to the perils of the journey, as suffer ourselves and families, and Benjamin among the rest, to perish for want of bread: it is no fault, but our wisdom and duty, to alter our resolutions when there is a good reason for so doing: constancy is a virtue, but obstinacy is not: it is God's prerogative to make unchangeable resolves.
