how about asking the Lord to defend you and your family? I am sure that he will not fail.
I'd rather copy Jesus and drive the wicked intruders out of my house, as He drove the thieves out of His Father's house.
There is a story somewhere in the Old Testament, where a godly King was out in battle, and he was surrounded by his enemies, and was outnumbered, and would have surely died. He cried out to the Lord, and the Lord delivered him. Not sure if I got this completely right
There are a few stories such as that. I'm sure you could find them with a little study. However, how the Lord usually helped ended up in the use of physical weapons to destroy the enemies of the people of God.
1. I already quoted Psalm 144:1, when the Lord taught David to fight physically. You did not answer that.
2. God gave the battle plan for the Second Battle of Ai, and helped His people who trusted Him.
3. Jonathan and his armorbearer prayed for God's guidance and help, then went up and killed a bunch of Philistines with the sword (1 Samuel 14).
4. David prayed for help against the Philistines, and God gave the battle plan: flank the enemy while I move in the mulberry trees (2 Samuel 5:22-25).
5. Etc., etc. I could take the time to give many more examples.
I love #4:
22 And the Philistines came up yet again, and spread themselves in the valley of Rephaim.
23 And when David enquired of the LORD, he said, Thou shalt not go up; but fetch a compass behind them, and come upon them over against the mulberry trees.
24 And let it be, when thou hearest the sound of a going in the tops of the mulberry trees, that then thou shalt bestir thyself: for then shall the LORD go out before thee, to smite the host of the Philistines.
25 And David did so, as the LORD had commanded him; and smote the Philistines from Geba until thou come to Gazer.
If I were in a similar situation, with violent enemies entering my house to kill me and rape my wife, I would pray for the Lord's help as I used my sword to defend us.
