(3.) Wood (Judges 16:3) probably.
At the gates of cities courts of justice were frequently held, and hence "judges of the gate" are spoken of (Deuteronomy 16:18; 17:8; 21:19; 25:6, 7, etc.). At the gates prophets also frequently delivered their messages (Proverbs 1:21; 8:3; Isaiah 29:21; Jeremiah 17:19, 20; 26:10). Criminals were punished without the gates (1 Kings 21:13; Acts 7:59). By the "gates of righteousness" we are probably to understand those of the temple (Psalm 118:19). "The gates of hell" (R.V., "gates of Hades") Matthew 16:18, are generally interpreted as meaning the power of Satan, but probably they may mean the power of death, denoting that the Church of Christ shall never die.
