You are my battle-ax and sword," says the LORD. "With you I will shatter nations and destroy many kingdoms. With you I will shatter armies, destroying the horse and rider, the chariot and charioteer. With you I will shatter men and women, old people and children, young men and maidens. With you I will shatter shepherds and flocks, farmers and oxen, captains and rulers. "As you watch, I will repay Babylon and the people of Babylonia for all the wrong they have done to my people in Jerusalem," says the LORD. "Look, O mighty mountain, destroyer of the earth! I am your enemy," says the LORD. "I will raise my fist against you, to roll you down from the heights. When I am finished, you will be nothing but a heap of rubble. You will be desolate forever. Even your stones will never again be used for building. You will be completely wiped out," says the LORD. (Jeremiah 51:20-26)
Anyone who is captured will be run through with a sword. Their little children will be dashed to death right before their eyes. Their homes will be sacked and their wives raped by the attacking hordes. For I will stir up the Medes against Babylon, and no amount of silver or gold will buy them off. The attacking armies will shoot down the young people with arrows. They will have no mercy on helpless babies and will show no compassion for the children. (Isaiah 13:15-18 NLT)
"Then I heard the LORD say to the other men, "Follow him through the city and kill everyone whose forehead is not marked. Show no mercy; have no pity! Kill them all – old and young, girls and women and little children. But do not touch anyone with the mark. Begin your task right here at the Temple." So they began by killing the seventy leaders. "Defile the Temple!" the LORD commanded. "Fill its courtyards with the bodies of those you kill! Go!" So they went throughout the city and did as they were told." (Ezekiel 9:5-7 NLT)
There is no such thing in Islam or the quran in fact there is the absolute opposite. Muhammad (pbuh) forbade killing of women and children even livestock. The bible teaches even murder donkies and sheep, spare no one
