This God speaks to the prophet, either to inform him that there is no hope of this people’s reformation, Jer_8:5; therefore he expresseth a deceitful people by the abstract,
deceit, i.e. nothing among them but deceit one to another, and hypocrisy towards me, as Psa_109:2, and vanity for vain men, Job_35:13; or to caution and advise him how to behave himself among such a people, that he be very wary he be not insnared by them, Jer_12:6.
They refuse to know me; either hoping to shift well enough by their several means they think to use, they are careless of turning to me, Jer_8:5; or by hearkening to their false prophets, who have all along deceived them, they obstinately reject my ways and counsels, Psa_36:1-4 82:5.
