Charles Ellicott Commentary 2 Chronicles 19:6

"and said to the judges, Consider what ye do: for ye judge not for man, but for Jehovah; and [he is] with you in the judgment." — 2 Chronicles 19:6 (ASV)

Ye judge not for man, but for the Lord. —It is not for man that you will judge, but for Jehovah, as His vicegerents, and ministers of His will. (Compare to Romans 13:1-4.)

Who is with you in the judgment. —This rightly gives the sense of the brief words: “and with you in word of doom.” That is, Jehovah will be present with you at the time of your giving sentence. (See on 2 Chronicles 20:17, and compare to Psalms 82:1-4: God standeth in God’s Assembly; in the midst of gods (that is, judges) He judgeth.)

The Septuagint and Vulgate misunderstand the passage, but the Syriac renders it: Be strong, and judge true judgment, and the Lord will be with you for ever. (Compare also to Deuteronomy 1:17: The decision belongeth to God; and Exodus 21:6.)

The name “Jehoshaphat” denotes Jehovah judgeth.
