Mosiah 10:9

And it came to pass that I caused that the women and children of my people should be hid in the wilderness; and I also caused that all my old men that could bear arms, and also all my young men that were able to bear arms, should gather themselves together, to go to battle against the Lamanites; and I did place them in their ranks, every man according to his age.

I had the women and children hide in the wilderness. I gathered all the old men who could fight and all the young men who could fight. We got ready to battle the Lamanites. I put each man in line by his age.

I had all the women and children hidden in the wilderness. Then I gathered every man who could fight—old and young alike—and organized them into ranks by age to face the Lamanites in battle.
