Matthew Henry Presbyterian @wholebiblehenry

Here is, I. A law against deceitful weights and measures: they must not only not use them, but they must not have them, not have them in the bag, not have them in the house (Deu 25:13, Deu 25:14); for, if they had them, they would be strongly tempted to use them.

John Gill Reformed Baptist @doctorgill

For all that do such things,.... Keep, different weights and measures, and make use of them to defraud their neighbours in buying and selling: and all that do unrighteously; what is not just and right between man and man, in any other instance whatever: are an abomination unto the Lord thy God; both they and their actions; he is a righteous God, and loves righteousness...

Deu 25:13-16 The duty of integrity in trade is once more enforced in Deu 25:13-16 (as in Lev 19:35-36). “Stone and stone,” i.e., two kinds of stones for weighing (cf. Psa 12:3), viz., large ones for buying and small ones for selling. On the promise in Deu 25:15, see Deu 4:26; Deu 5:16; Deu 25:16, as in Deu 22:5; Deu 18:12, etc.
