you who inflame yourselves among the oaks,
under every green tree,
who slaughter the children in the ravines,
under the clefts of the rocks? Bible see other translations

“inflame yourselves.” This very graphic language pictures the sexual excitement of the people involved with pagan ritual sex, who picked cool spots underneath the trees for their rituals, and then slaughtered their children to pagan gods. This horrific sin opened the doors for God’s judgment and attacks by demons.

Commentary for: Isaiah 57:5
