Thus the Jews smote all their enemies with the stroke of the sword, and slaughter, and destruction, and did what they would unto those that hated them. Esther 9:5
Mordecai, is now the second in command under king Ahasuerus. The king’s command given through Haman could not be reversed, but with the stroke of a pen Mordecai with the authority of the king wrote another command that allowed the Jews to protect and defend themselves.
And, they did. If you will notice the law that was given the evil ones attacking them could be killed, and all their possessions taken as well, but they did not take possessions.
This shows us that when evil flaunts itself against God’s people to steal, kill, and destroy God’s people have the right to defend themselves. That is so in any era of time. Not to provoke a fight, but to fight when they are provoked and life and property is on the line.
Jesus even told His disciples at one point to get some swords (Luke 22:36-38). We do not go looking for a fight. We are to be faithful to God in doing what He has given us commandment to do, and commissioned to do as well.
Remember Nehemiah while building the wall armed the workers even while they worked. They were working, not looking for a fight, just being faithful to do the work of the Lord.
Be faithful to do the work of the Lord, and do not fear, be courageous, and stand and fight if you must. In the name of our blessed Savior who died on the cross for our sins, was buried and He rose again. He fought that battle for us, and when we are faithful in service to Him He is faithful to fight for us now.
