4. For thus hath Jehovah said to me. The Prophet adds this verse, that it may not be thought that the Lord leaves us destitute of necessary means; for if, while he forbids us to place our confidence in creatures, he did not promise us any assistance, we might complain that he gave ground for despair, and not for consolation; as we saw, a little before, that men are more careful and attentive than they ought to be, because they think that they will be deficient in thoughtfulness, if they rest satisfied with God alone, and abstain from forbidden means. He therefore takes away every excuse, when he promises that he will be a faithful guardian to us; for what pretense can be left, if we despise the salvation which he offers to us of his own accord? It is therefore as if he had said, “The Lord assists, and will assist; he forbids you to ask assistance from the Egyptians.” By comparing himself to a lion, a very powerful animal and keenly bent on prey, he employs a very appropriate comparison, to shew that he is in the highest degree both able and willing to defend us.
In the second part of the comparison, the Prophet dwells largely on the great eagerness with which the Lord takes hold of his people, keeps them near himself, preserves them from being carried off, and defends them against all dangers; while he also points out that strength and power which no arms and no forces can resist. Now, it is impossible that comparisons should hold on every point, nor is it necessary, but they ought to be suitable to the subject which is handled. Since therefore we know that the Lord loves us so much and takes such care of us, must we not be worse than mad if we despise him, and seek other aids, which will not only be useless but destructive to us?
