KJV: For if thou altogether holdest thy peace at this time, then shall there enlargement and deliverance arise to the Jews from another place; but thou and thy father's house shall be destroyed: and who knoweth whether thou art come to the kingdom for such a time as this?
NASB: "For if you remain silent at this time, relief and deliverance will arise for the Jews from another place and you and your father's house will perish. And who knows whether you have not attained royalty for such a time as this?"
