What does the word harnessed mean in Exodus 13 verse 18?

The Literal Bible [LIT] says: "...and ARMED [CHAMUSH - khaw-moosh': ...staunch, i.e. able-bodied soldiers..."] went up the sons of Israel from the land of Egypt." (Literal Bible w/Strong's Definitions)

"So God led them along a route through the wilderness toward the Red Sea, and the Israelites left Egypt like a MARCHING ARMY." (NLT New Living Translation)
