The name Purim comes from the word "pur" which means "lot" because Haman Cast Pur (which is a lot) (Esther 3:7) to determine the day the Jews would be destroyed and it fell on 12th month known as Adar.
The Bible tells us that The lot is cast but the entire outcome is from the Lord. (Proverbs 16:33)
This Proverb can be taken at its literal meaning i.e. when the lot is cast or the dice is thrown, God sets the results by determining how they will land or fall because this decides the events that follow the lot casting or dice throwing event.
The Purim events show us that this Proverb also has a deeper meaning because when the lot casting determined that the Jews would be destroyed on 13th day of the 12th month of Adar (Esther 3:13), God even went further and determined the entire outcome of that day.
This is because on that day, instead of the Jews being killed by their enemies, the Jews killed their enemies (Esther 9:1).
Therefore even if your enemies have consulted seers, cast lots and determined the best day and the best method to destroy you, do not be dismayed.
Do not distressed because God sets the results and determines the final outcome.
Do not even be afraid if you are fast approaching the Day of Doom that has been determined by your enemies because God can turn it around even if they have passed an irrevocable decree the way Haman's decree to destroy the Jews was made irrevocable by the King's signet.
God can still turn it around because He tells us, My thoughts are not your thoughts and your ways are not My ways, says the Lord. For as the heavens are higher than the earth, so are My ways higher than yours and My thoughts above your thoughts. (Isaiah 55:8-9)
