Sword of your majesty is one of a pair of expressions used as names for God. The kherev is the most common Hebrew word for a military sword. Archeological evidence shows that swords developed through the centuries. They went from short straight weapons like daggers to curved blades and, under the Philistines, to long straight swords.
When Moses called God the sword of your majesty, it pointed to God’s readiness to judge Israel’s enemies and to rescue His people.
Sword of your majesty in Hebrew:
Kherev ga’avatekha
Strong’s Concordance numbers: 2719, 1346
Bible reference: Deut. 33:29
Blessed are you, O Israel;
Who is like you, a people saved by the Lord,
Who is the shield of your help
And the sword of your majesty!
So your enemies will cringe before you,
And you will tread upon their high places. (Deuteronomy 33:29)
Other versions translate this name of God differently. The NIV has “your glorious sword,” the Message Bible has “sword who brings triumph,” and the KJV has “sword of Thy excellency.”
