Praise The Lord!!! Most likely David is experiencing two-faced, double tongued people. It may seem like they are on your side, that they are speaking the same language, they're nodding in agreement with everything you say, they say, "Your the best" but their heart is in another place, devising schemes. But The Lord knows their heart. He knows what they think. The Lord cares and loves His people. He will not allow it to prosper. The Words of the Lord are pure Words and you can hang on every word that proceeds out of the mouth of the Lord. It will not return void it will do what it is sent forth to do. Follow The Word and don't worry about people. People will be people always changing. BUT our GOD is absolute and is the same, today, yesterday and forevermore.
What is GOD saying?
Meditate on the Word Of GOD.
For the director of music. According to sheminith. A psalm of David. Help, Lord, for no one is faithful anymore; those who are loyal have vanished from the human race. Everyone lies to their neighbor; they flatter with their lips but harbor deception in their hearts. May the Lord silence all flattering lips and every boastful tongue— those who say, “By our tongues we will prevail; our own lips will defend us—who is lord over us?” “Because the poor are plundered and the needy groan, I will now arise,” says the Lord. “I will protect them from those who malign them.” And the words of the Lord are flawless, like silver purified in a crucible, like gold refined seven times. You, Lord, will keep the needy safe and will protect us forever from the wicked, who freely strut about when what is vile is honored by the human race Psalms 12 NIV
