Surely there is no enchantment against Jacob, neither is there any divination against Israel. (Numbers 23:23)
How this should cut up root and branch all silly, superstitious fears! Even if there were any truth in witchcraft and omens, they could not affect the people of the Lord. Those whom God blessed, devils cannot curse.
Ungodly men, like Balaam, may cunningly plot the overthrow of the Lord’s Israel; but with all their secrecy and policy they are doomed to fail. Their powder is damp; the edge of their sword is blunted. They gather together; but as the Lord is not with them, they gather together in vain. We may sit still and let them weave their nets, for we shall not be taken in them. Though they call in the aid of Beelzebub and employ all his serpentine craft, it will avail them nothing: the spells will not work, the divination will deceive them. What a blessing this is! How it quiets the heart! God’s Jacobs wrestle with God, but none shall wrestle with them and prevail. God’s Israels have to prevail against them. We need not fear the fiend himself, nor any of those secret enemies whose words are full of deceit and whose plans are deep and unfathomable. They cannot hurt those who trust in the living God. We defy the devil and all his legions.
