'Armies' in the Bible

Now the Philistines gathered their armies for battle; and they were gathered at Socoh which belongs to Judah, and they camped between Socoh and Azekah, in Ephes-dammim.

Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span.

Then David spoke to the men who were standing by him, saying, “What will be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should taunt the armies of the living God?”

Your servant has killed both the lion and the bear; and this uncircumcised Philistine will be like one of them, since he has taunted the armies of the living God.”

Then David said to the Philistine, “You come to me with a sword, a spear, and a javelin, but I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have taunted.

Now the Philistines gathered together all their armies to Aphek, while the Israelites were camping by the spring which is in Jezreel.
