“Those who hate the Lord would pretend obedience to Him, And their time of punishment would be forever.

Psalms 81:15 (NASB)

Sometimes we add words to the primary report or saying hoping to bring out important aspects of meaning.  This verse illustrates the unnecessary addition of “obedience”.  Since God cannot be deceived  faking it with

God’s enemies are all over the world, including ancient Israel.  Ignorance about what Yahweh had done was not a Gentile thing.  Apparently,  noble people can snap in a trice, making up their own version of the facts.  Sarah, mother of the Hebrew people did it and some prophets were known  to manipulate the truth.

You did.  I did not.  Dos too.

Sarah denied it however, saying, “I did not laugh”; for she was afraid. And He said, “No, but you did laugh.”

Genesis 18:15

Also it will come about in that day that the prophets will each be ashamed of his vision when he prophesies, and they will not put on a hairy robe in order to deceive;

Zechariah 13:4

I do not mind saying that the King James translation is off target.  It addresses neither the Hebrew kachash nor the Septuagint’s pseudomai.  Both mean to misrepresent.  Misrepresentation can be carefully crafted narratives or calculated to mislead.  There is the widespread fact that people in New Testament times were in the grip of stories that had circulated from antiquity.  See what Peter and Paul say about this.

For we did not follow cleverly devised tales when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of His majesty.

2 Peter 1:16

7. But have nothing to do with worldly fables fit only for old women. On the other hand, discipline yourself for the purpose of godliness; 8. for bodily discipline is only of little profit, but godliness is profitable for all things, since it holds promise for the present life and also for the life to come.

1 Timothy 4:7-8

There is also faking it by planning the answer to an embarrassing question. When the people in charge of the temple in Jerusalem decided to challenge Yeshua’s authority he asked him about John the Baptist’s authority. They, realizing that he had them between a rock and a hard place, plotted what they we going to say.  See the “faking it” play out in Matthew 21:23ff

I lie contrary to one or several divine commands, but lying to God never gets off the ground.   Two weighty matters emerge from this saying in Psalm 81.  None of them appears to be lying, even though the people as a whole have falsified their experience with Yahweh.  They are slow to admit that they had consistently rejected what Yahweh had to say.  There was no truth between Yahweh and his people.  Eternal punishment is not for merely telling lies but for being duplicitous in attitude, word, and deed. Being a friend of God calls for brutal authenticity which has no faking in it.
