When thou dost lend thy brother anything
Any sum of money he stands in need of, or demanded a debt of him, as Jarchi; money he is indebted to thee, which is the sense of the Septuagint version; and he is not able to pay it, but offers something: in pawn till he can pay it:
thou shall not go into his house to fetch his pledge;
which would be an exercise of too much power and authority, to go into a neighbour's house, and take what was liked; and besides, as no doubt he would take the best, so he might take that which the poor man could not spare: and indeed, according to the Jewish canons F11, he could not take any pledge at all, but with the knowledge, and by the leave, of the sanhedrim, or court of judicature.
