They shall justify the righteous - This is a very important passage, and is a key to several others. The word צדק tsadak is used here precisely in the same sense in which St. Paul sometimes uses the corresponding word δικαιοω, not to justify or make just, but to acquit, declare innocent, to remit punishment, or give reasons why such a one should not be punished; so here the magistrates הצדיקו hitsdiku, shall acquit, the righteous - declare him innocent, because he is found to be righteous and not wicked: so the Septuagint: και δικαιωσουσιν τον δικαιον they shall make righteous the righteous - declare him free from blame, not liable to punishment, acquitted; using the same word with St. Paul when he speaks of a sinner's justification, i. e., his acquittance from blame and punishment, because of the death of Christ in his stead.
Render it:
(1) If there be a controversy between men, and they come to judgment, and the judges judge them, and justify the righteous and condemn the wicked (compare the marginal reference. and Exodus 23:7; Proverbs 17:15);
(2) then it shall be, etc.
Deuteronomy 25:2
Scourging is named as a penalty in Leviticus 19:20. The beating here spoken of would be on the back with a rod or stick (compare Proverbs 10:13; Proverbs 19:29; Proverbs 26:3).
