Christ is the universal Judge. Probably the wounding the heads refers to the destruction of Satan, whose heart shall be bruised in every place, and in all countries throughout the earth. Jesus will himself do this; and he will do it also for his people; for, as the God of peace, he will bruise Satan under their feet shortly. Romans 16:20.
