"Much people of Israel died" of the bites of these serpents, which, disturbed by the travellers as they went sullenly and carelessly along, issued from crevices of the ground and from the low shrubs in which they lurked, and at once fastened on feet and hands. The peculiar character of the new enemy caused universal alarm. As one and another fell writhing to the ground, and after a few convulsive movements died in agony, a feeling of terrified revulsion spread through the ranks. Pestilence was natural, familiar, as compared with this new punishment which their murmuring about the light food and the thirst of the desert had brought on them. The serpent, lithe and subtle, scarcely seen in the twilight, creeping into the tents at night, quick at any moment, without provocation, to use its poisoned fangs, has appeared the hereditary enemy of man. As the instrument of the Tempter it was connected with the origin of human misery; it appeared the embodied evil which from the very dust sprang forth to seek the evil-doer. Many ways had Jehovah of reaching men who showed distrust and resented His will. This was in a sense the most dreadful. The serpents that lurked in the Israelites' way and darted suddenly upon them are always felt to be analogues of the subtle sins that spring on man and poison his life. What traveller knows the moment when he may feel in his soul the sharp sting of evil desire that will burn in him to a deadly fever? Men who have been wounded can, for a time, hide from fellow-travellers their mortal hurt. They keep on the march and make shift to look like others. Then the madness reveals itself. Words are spoken, deeds are done, that show the vile inoculation taking effect. By-and-by there is another moral death. Humanity may well fear the power of evil thoughts, of lusts, of envious feelings, that serpent-like attack and madden the soul; may well look up and cry aloud to God for a sufficient remedy. No herb nor balm to be found in the gardens or fields of earth is an antidote to this poison; nor can the surgeon excise the tainted flesh, or destroy the virus by any brand of penance.
