'Themselves' in the Bible

They also built for themselves high places, sacred pillars, and Asherah poles on every high hill and under every green tree;

Let two bulls be given to us. They are to choose one bull for themselves, cut it in pieces, and place it on the wood but not light the fire. I will prepare the other bull and place it on the wood but not light the fire.

They shouted loudly, and cut themselves with knives and spears, according to their custom, until blood gushed over them.
