Psalm 78:36
KJV
Nevertheless they did flatter him with their mouth, and they lied unto him with their tongues.
LSB
But they deceived Him with their mouth And lied to Him with their tongue.
For context, this verse is describing the children of Israel in the wilderness. Their intention was not to deceive God, but they certainly did have flattering mouths, speaking words without integrity because their heart was not right with him.
