'Perish' in the Bible

For if indeed you keep silent at this time, relief and deliverance will arise for the Jews from another place, and you and the family of your father will perish. Who knows? [Perhaps] you have come to a royal position for a time such as this."

"Go, gather all the Jews that are found in Susa and fast for me; do not eat or drink [for] three days, both night and day. I and my young girls will fast likewise, and then I will go to the king, which [is] not according to the law; if I perish, I perish.
