Thy shoes shall be iron and brass; and as thy days, so shall thy strength be.- Deuteronomy 33: 25
The Revised Version puts this in the margin: He shall have protection for his feet. The chief objection that has been raised to this is that it would be a very unusual thing for shoes to be made of iron and brass. Such a thing is not heard of anywhere else in Scripture, neither is it according to Oriental custom. For that reason I judge that the interpretation is the more likely to be correct, since the protection which God gives to His people is unusual. No other feet shall wear so singular a covering; but those who are made strong in the Lord shall be able to wear shoes of iron, and the Lord shall give them sandals of brass.
God’s people are a peculiar people, and everything about them is peculiar…You have peculiar difficulties, you are a peculiar people, you traverse a peculiar road, you have a peculiar God to trust in, and you may, therefore, find peculiar consolation in a peculiar promise: “Thy shoes shall be iron and brass.”…But what does this mean-“thy shoes shall be iron and brass”?..Does it not mean that our feet, tender and unprotected by nature, shall receive protection-protection from God? Our feebleness and necessity shall call upon God’s grace and skill, and He will provide for us, and give to us exactly what we, by reason of our feebleness, so much need.~ C.H. Spurgeon
