II Kings 6:19
Here Elisha lies to his enemies who have been struck blind after his prayer to that end. Elisha tells the blind Syrian company that he will lead them to Elisha but instead leads them into entrapment and surrender.
“Like Rahab in Jericho and the Hebrew midwives to Pharaoh, Elisha saw no morality in telling the truth to men determined to do evil and murder…. God does not condemn Elisha. Truth must serve God and His justice. Not evil.”
The Pietism of modern-day Christianity insists that when Abraham lied twice about Sarah being his sister and not his wife that Abraham sinned even though the Scripture never declares that. As Rushdoony says above we do not owe the truth to those who will use the truth to persecute God’s people, or who will use the truth to kill the judicially innocent.
