Leviticus 19:35

Ye shall do no unrighteousness in judgment, &c.— i.e. "Ye shall conduct yourselves through life, and especially in all your commerce and dealings, by the strictest rules of exact justice." It is to be observed, that, to prevent all fraud in weights and measures, the standard of them was kept in the sanctuary: compare Exodus 30:13 with 1 Chronicles 23:29. The word rendered weights, is stones in the margin of our English Bibles, because stones were used as well for weights as for plummets in building.

Note; 1. This benevolent command, that strangers are to be treated kindly. The remembrance of their own state in Egypt was to teach the Israelites to pity others. Strangers must not be oppressed, nor defrauded, nor reproached, but loved as brethren, and treated with equal affection. They who are strangers have a right to peculiar kindness: it is enough that they are removed from their domestic comforts; they need not have their absence more embittered by ill usage. 2. Justice must be observed in measures, weights, and scales. To sell less than weight or measure, is, at least, equally criminal with other acts of theft, which, though man may never discover, shall be severely visited when God weighs such in his balances, and finds them wanting. 3. All God's statutes must be observed and done; head, heart, and hand, must concur. Remember, No man sincerely obeys God who makes any reserves; and he will never really please him by obedience to any one command, who does not in simplicity seek to observe them all.
