"Therefore I stationed some of the people behind the lowest points of the wall at the exposed places, posting them by families, with their swords, spears and bows. After I looked things over, I stood up and said to the nobles, the officials and the rest of the people, “Don’t be afraid of them. Remember the Lord, who is great and awesome, and fight for your families, your sons and your daughters, your wives and your homes.”There were even some brave soldiers who went into battle no matter what, as seen in 1 Samuel 14:52:
"When our enemies heard that we were aware of their plot and that God had frustrated it, we all returned to the wall, each to our own work.
"From that day on, half of my men did the work, while the other half were equipped with spears, shields, bows and armor. The officers posted themselves behind all the people of Judah who were building the wall. Those who carried materials did their work with one hand and held a weapon in the other, and each of the builders wore his sword at his side as he worked. But the man who sounded the trumpet stayed with me."
"All the days of Saul there was bitter war with the Philistines, and whenever Saul saw a mighty or brave man, he took him into his service."
