'Army' in the Bible

"Then we turned, and we went up the road to Bashan, and Og the king of Bashan came out to meet us, he and all [of] his army for the battle [at] Edrei.

And Yahweh said to me, 'You should not fear him, for I have given him and all [of] his army and his land into your hand. And [so] you will do to him as you did to Sihon the king of the Amorites, who [was] reigning in Heshbon.'

And [so] Yahweh our God also gave Og the king of Bashan, and all of his army into our hand, and we struck him down until not a survivor remained to him.

and what he did to the army of Egypt and to their horses and to their chariots, [and] how he made the water of the {Red Sea} flow over them, {when they pursued after them}, and so Yahweh has destroyed them, {as is the case today},

"If you go out to war against your enemies and you see a horse and a chariot, {an army} larger that you, you shall not be afraid because of them; for Yahweh your God [is] with you, the one who brought you from the land of Egypt.

And {when the officials have finished speaking} to the army troops, then they shall appoint commanders of divisions at the head of the troops.

"When a man takes a new wife he shall not go out with the army, and {he shall not be obligated with anything}; he shall be free from obligation, {to stay at home} for one year, and he shall bring joy [to] his wife that he took.
