Nevertheless they did flatter him with their mouth, and they lied unto him with their tongues. Nevertheless they did flatter him with their mouth - What idea could such people have of God, whom they supposed they could thus deceive? They promised well, they called him their God, and their fathers' God; and told him how good, and kind, and merciful he had been to them. Thus, their mouth flattered him. And they said that, whatever the Lord their God commanded them to do, they would perform.
And they lied unto him - I think the Vulgate gives the true sense of the Hebrew: Dilexerunt eum in ore suo; et lingua sua mentiti Bunt ei, - "They loved him with their mouth; and they lied unto him with their tongue." "That is," says the old Psalter, "thai sayde thai lufed God, bot thai lighed, als thair dedes schewes; for thai do noght als thai hight; for when God ceses to make men rad; than cese thai to do wele."
