When a man marries a bride, he shall not go out in the army or be assigned…One may not take in collateral a hand mill…for one would be taking a life as collateral. Why do these verses follow one another? A lender may not take as collateral something that preserves an individual and gives them a livelihood. Similarly, explains the Netziv, marriage sustains the individual and therefore the army or government is warned not to separate the new couple – this is why these verses follow each other.
