[But] thou shall have a perfect and just weight, a perfect
and
just measure shall thou have
That is, full weights, and full measures; and such as are alike,
and everywhere used, according to the standard of the country;
(See Gill on
Leviticus 19:36);
that thy days may be lengthened in the land which the Lord
thy God
giveth thee;
long life was always reckoned a blessing, and is frequently
promised to, obedience, and particularly long life in the land of
Canaan; which was a most delightful and fruitful land, and which
a man might wish to live long in; deceitful men, are threatened
with not living half their days, and such may they be said to be
that use false weights and measures, ( Psalms 55:23
) .
